MS Access Control Source DLookUp - ms-access

I haven't been able to make a DLookUp function work in an Access report. I can't figure out what I'm doing wrong.
The report is getting its dataset from a query called Aggregate Query. This query builds a dataset from 20 related tables using CustomerID as the primary key in one table and as a foreign key in the other 19. CustomerID is specified by an open Form with the desired customer's record displayed, including the CustomerID field.
This means Aggregate Query has several rows for one specific CustomerID. One field, Needs Notes, will have the same content on every row. What I'm having trouble with is getting only one of these rows displayed in the subreport, and subsequently on the parent report.
If there are six rows, say, in Aggregate Query, then the same Needs Notes field is repeated six times. I want it to appear only once in the subreport.
I couldn't choose only the first row from Aggregate Query. If this can be done that'd be great. I don't know.
So I created another query, Need-notes Only Query, which always gives me only one row every time. So far so good. Now I want the contents of the Needs Notes field to appear all by itself in the subreport. To do this I selected the text box and entered the following into the Control Source parameter:
=DLookUp("[Needs-notes Only Query]![Needs Notes]","Needs-notes Only Query")
No dice. I get six rows saying #Error.
Is there a way I can get just one row of the Needs Notes field into my report?

Split field and table names:
=DLookUp("[Needs Notes]","[Needs-notes Only Query]")

Can you link multiple tablixes on a key field in a single SSRS report?

I am creating a report in SSRS to show evaluation scores. It has three sections, and I need to link them all together on the PreceptorID field (2108 in this case). The top two sections are from the same query. I am filtering the results in each one to separate the counts because they have different column names. The third section is a subreport showing comments from evaluators. It also has the PreceptorID field in the data but is not displaying it. It has two parameters that should be populated by the main report query, but that does not appear to be happening. The report is returning all comments instead of only the ones with the matching PreceptorID.
This first image is from Crystal Reports showing how the finished product should look.
This is what I am getting from SSRS. It is showing counts for multiple people at the top. The counts in the middle are actually correct. They are all for the one person. The next person's counts are on the next page. The comments at the bottom are also not filtering on the one PreceptorID.
This image showing the subreport parameter that should be linking it back to the main query.
How can I tell all three sections to only return data for the same person on one page, and another person on the next page?
I would redesign the report structure slightly. This is only my personal preference, there are several ways to achieve this but I find this way easier to manage and maintain.
You'll need two subreports and a master report.
You already have the 2nd subreport so no extra work required there.
I would take you current report, strip out the link to the current subreport and change it so it only processes a single person (just like your existing sub report).
So SubReport1 will have the two tables from your current main report only. It will only accept a single person as a parameter (or pair of parameters in your case)
SubReport2 will be your current subreport. Again it only accepts a single person.
Next create a new report. This will be the master report.
Add a dataset that contains just enough info for list of people you want to report over. So the dataset query might be as simple as
SELECT PreceptorID, ClerkshipID FROM myTable ORDER BY PreceptorID
Add a table to this report and set it's dataset property to the dataset you just created.
Change the default (details) row group to group and order by whatever makes each record unique (maybe both the two columns listed above, may only one will be required, only you will know this).
Right-Click on the row header to the left of your table and do "Insert Row => Inside Group Below".
Remove all but one column
You should now have a table with 2 rows per group.
Right click the top cell in the group and do "Insert => Subreport", go to the subreport properties and point this to SubReport1 (or whatever you called it) and set the parameters has you have done previously.
Repeat this for second row, this time pointing to your second subreport.
In the row group properties, set page breaks to "Between each instance"
That should be it. This was done from memory so might not be 100% but based on the info in your question you should be able to work it out from here.
Things to check if this is not working
Open each subreport and test it by passing in parameters manually. Each subreport should only be returning data for a single person.
The master report should have a dataset that returns each person once i.e. if there are 10 people in total this dataset should only contain 10 rows.
The table in the master report should contain only two rows
Both rows must be EITHER within the same row group, or, if you have no other row groups, they will both be in the detail row group.
The report design should look something like this if you have a row group by person
or like this if you only have detail rows.
Finally, make sure the parameters you pass to your subreports are the Field values from your master report's dataset, NOT your master reports parameters.

Unique values in Report Builder Parameters without rerunning new query

I'm using Report Builder 3 which runs a stored procedure and displays a simple table. Next, we would like to filter based on the first column of data. The first column of data might have 20 rows, and 3 possible values.
How can I make Report Builder display those 3 values in the parameter dropdown, without rerunning a SP or Query from the server?
(Running the SP that obtains the data takes several seconds, and it is not reasonable to rerun another query in order to populate the parameter dropdown)
What I've tried:
1) I create a parameter dropdown and select the column name as values for the dropdown. Instead of getting 3 unique values, 20 rows appears in the parameter dropdown, with duplicates corresponding to the original dataset results. How can I make them unqique?
2) Grouping by the values in the first column. Grouping works, but we would still like to display a parameter dropdown that contains unique values from column one.

SSRS Report - Subgroup Totals

I have an SSRS report that is currently pulling a single dataset. This dataset contains records of inventory we have. Each record is a separate asset.
I want my report to group by a certain field, and then subgroup by certain criteria that are determined with a couple different fields. Basically there is one parent group, and three adjacent subgroups. My grouping functionality is working correctly, however I am finding it difficult to add totals to each of the adjacent subgroups. When I add a total, it is totaling the specific field within the scope of the entire dataset, instead of limiting the total to just that subgroup.
How can I add totals per field within subgroup?
EDIT: Added sample data and explanation:
You can ignore the function code field, that is what I am using to group on the parent group.
asset number,description,first year,acquisition cost,function code
190,random asset,2008,5000,100
193,random asset45,2008,56000,100
197,random asset26,2014,3000,100
191,random asset27,2014,7000,100
192,random asset36,2013,15000,100
I can't seem to attach screenshots, so here goes..
In the report you can see three subgroups; Assets, AssetAdditions, AssetDeletions. In the tablix, you can see where these groups are positioned. You can also see a row directly beneath the group that is supposed to total the subgroup at the end. However, for some reason the scope is only taking into account the entire dataset. I have tried to modify the expression in the Sum function [Sum(acq_cost), "Assets"], adding in the scope parameter but then it does not allow me to even run the report. It yells at me saying that "Assets" is an invalid scope.
The easiest way I have done this in 2012 VS is to have it return as part of the data set and have it sum up the value.
For instance if you have a quantity for inventory, and you have a subset where you only want the total quantity for that set, you add another column to your dataset called TotalSetQuantity and the subtotal field will have the expression =SUM(Fields!TotalSetQuantity.Value) rather than =SUM(Fields!Quantity.Value).
You can try iif statements within your report like =sum(iif(Fields!ColA.Value=1,Fields!Quantity.Value,0) but I had some troubles getting that to work.
Hope that helps, I ran into this issue this past week and the first option worked like a charm for me.

use access form to edit data from a query result

I'm brand new to Access 2010, well to Access in general. I have a query that returns 10 columns (the query is called pending_review, the source is a table called escalations) in the results, some of those fields are blank since they have to be reviewed. One of the resulting columns is the primary key.
So this is my problem: I need a to create a form where I can type the primary key and the fields on the form will populate with the info from that row so I can fill the blank spaces with information that I now have and then update the table.Once the table is updated, that row should no longer show on the query results.
What I have done is that I created the form, but I don't know how to do the part of typing the primary key and everything gets populated. A solution would be to make a combo box that shows me the primary keys of the rows in the query results, so that every time i edit something in one of those fields for the query to be run again and reduce the number of options in the combo box.
Question is, how do i do that? or is there an easier and better way to do it?
Thanks in advance!!
Can you not just create a new form using the pending_review query as a data source? Access makes it very easy--you can just use the form wizard. This gives you a form in which you can edit one row at a time. Presumably the pending_review query has a filter condition that checks for certain fields being blank (null) or not. If you finish editing a result row in the form, and refresh the form, the row should then disappear from the form because it will no longer be returned by the pending_review source query.
Even if you need to do something more complex, this should at least be a good start.

SSRS - Why is my table duplicating rows?

I am creating a report in SSRS. I have a table showing the date and time the report was generated, it's a single column table with one expression =Now() and is not linked to any datasets.
The trouble I am having is that it returns 77 rows all with the exact same date. My main dataset returns 77 rows in a different table but that table is not linked to this one in any way.
How can I stop it from returning so many rows? The reason I'm using a table and not a text box is because I want it to have the same look and feel as other data presented in my report i.e. Header Row and Data Presented underneath. There are a few tables that use the same approach and all of them are returning duplicate rows. As you can see from the image below, I just need the first row from each table.
EDIT: Looks like SSRS automatically references a dataset when I insert a new table. When I change the table properties dataset to none it returns an error. Is there a way around this? I don't want data from any dataset, just want to use an simple expression =now()
As you've seen, a Tablix requires a DataSet, and when you only have one DataSet in a report it will link to this DataSet automatically in some circumstances.
You've mentioned you don't want to use Textboxes, but this does seem like the easiest option.
If you're set on using a Tablix for ease of formatting, to prevent any repeating rows just delete the Details group that gets set up by default when you create a Table through the designer:
This leaves a table with one header row only - you can add more header rows as required:
The result is a table that will only display the header rows once, i.e. no repeating rows.
You can add Summary data or individual fields from the DataSet to these header rows; if no aggregation is specified it will just take the first row by default.
