I need some help with an Access expression. I keep getting a syntax error.
I'm trying to get a calculated field from the combination of another calculated field.
Note that the LaserCuttingRate field is also a Lookup field. So it's not a simple entry field. It becomes a selector of the 3 choices.
IIf([LaserCuttingRate]="200",([CuttingTime]*200/60),IIf([LaserCuttingRate]="400",([CuttingTime]*400/60),IIf([LaserCuttingRate]="100",([CuttingTime]*100/60)))
All help appreciated.

I think you're missing a final close bracket.
There are 6 open brackets ( but only 5 closing brackets )
UPDATE - second issue
Two extra issues
The checks on number either don't need, or shouldn't have double-quotation masks
The final IIF also needs a false clause at the end (in the example below, 0).
Try this - I have put it into an Access database scratch table and it worked. (If relevant, note that I had LaserCuttingRate and CuttingTime set as doubles, as well as the Result Type for the calculated column).
IIf([LaserCuttingRate]=200,([CuttingTime]*200/60),IIf([LaserCuttingRate]=400,([CuttingTime]*400/60),IIf([LaserCuttingRate]=100,([CuttingTime]*100/60),0)))

As the subject expresses, I'm trying to sum the values of a string field where spaces may exist. It must be done this way, unfortunately.
The database is very old. The original developer chose to make all fields Text fields; to get over the null value problems, a function was written in VB6 to replace any null value with a space. This cannot be changed.
Fast forward to now, I'm trying to create a report that sums the length field without changing spaces to nulls first, and it should be done entirely through the control source property of the report.
I've added some of what I've tried below, but every time the report is run, I receive:
Data Type Mismatch
...and I'm not sure how to get around it.
Ideally, I'd like to keep the users out of the database completely, and just add a combo box that lists the reports created in the database so they can be opened by name without having to run any additional update queries first.
=Sum(IIf([MY_LEN]<>" ",DCount("[MY_LEN]","MY_TABLE"),0))
=Sum(Nz(Iif(Trim([MY_LEN])='',Null,[MY_LEN]),0))
=DSum("[MY_LEN]","[MY_TABLE]","[MY_LEN]<>' '")
=Sum(Iif(Val([MY_LEN])>0,[MY_LEN],0))
=(SELECT Sum([MY_LEN]) AS MyLen FROM MY_TABLE WHERE (((MY_TABLE.[MY_LEN])<>' ')))
Is this possible?
Can't compare anything to Null. Can't say If x = Null Then because Null is undefined. So you can't test if undefined = undefined. Use If IsNull(x) Then in VBA and Is Null in query criteria. Don't really need IIf() for Sum() aggregate, other aggregates such as Count or Avg would.
To handle possible space, empty string, or Null for a text field holding numeric data.
=Sum(Val([MY_LEN] & ""))
Hello I have been trying to return the result of a DCount within an MS Access form. I have a field called "Process" which stores a process such as "Shipping" and Sub-Process field which stores text too e.g. "Engineering". I have another field which needs to store the count of how many shipping processes have a specific sub-process such as answering "how many sub-processes are there for each process?" called txtcountsubprocesses.
The related text field is saved as txtprocess and the count field (the one I can't seem to get right) has the name txtcountsubprocesses. In the Control Source property for txtcountsubprocesses I have the following expression:
=DCount([Sub Process],[LogisticsData],[Process]=txtprocess.text)
I receive the following error message: #Name?
I have tried multiple other ways of programming the DCount however the way mentioned above seems to be the closest I have to a possible answer. I have also checked the spelling of the table headers from [LogisticsData].
Is it possible to solve my problem using a DCount method like this?
Required output (sorry not sure how to put in a proper table):
Process ; Sub-process ; Sub-processCount (3 columns)
Shipping ; Engineering ; 5 (three pieces of related data - the number being what I need to produce)
Shipping ; Medical ; 4 (three pieces of related data - the number being what I need to produce)
Firstly, DCount needs string parameters to identify field and table name.
Secondly, if you want to include something from the current form, you can concatenate those strings, or use a form parameter.
Thirdly, you should almost never use .Text. Use .Value instead. You can only use .Text on controls that have focus.
So, with all these things fixed:
=DCount("[Sub Process]","[LogisticsData]","[Process]='" & txtprocess.Value & "'")
You might want to read into using parameters, since oddities might occur when the value is Null or contains single quotes
I have the following code and I now want to only show the max or distinct values for a single field within SSRS.
=Join(LookUpSet(Fields!Baseacctnbr.Value,
Fields!Baseacctnbr.Value,
Fields!Acctnbr.Value,
"DataSet1"), ",")
Right now with this expression the code brings back all the accounts, but it brings back multiples of the same account because of the SQL query and other data that is needed. I would like to only show the MAX or Distinct values of the AcctNbr on a single field within SSRS.
Is there a way to add the MAX expression to this existing expression?
UPDATE:
When I add the SSRS Code Block found on another question, then I receive an error message that states: "Too many arguments to 'Public Shared Function RemoveDuplicates(m_Array() As Object) As String()."
Thanks.
I removed the close brace and it worked fine. I had also entered this code before your response and it worked fine since the account is actually 8 characters long.
=Join(Code.RemoveDuplicates(LookupSet(Left(Fields!BaseAcctNbr.Value, 8), Fields!BaseAcctNbr.Value, Fields!AllPhase3AcctNbrs.Value, "DataSet1")), ",")
Thanks for your help!
So, I have a problem in Report Builder that is just driving me absolutely crazy.
I have two dataset; one called DS_Grades and the other DS_Pupils. I want to do a simple LookUp based on PupilID, a field that is in both datasets, and return a grade from DS_Grades into a Matrix based on DS_Pupils.
The formula I am using is:
=LookUp(Fields!PupilID.Value, Fields!PupilID.Value, Fields!Grade.Value, "DS_Grades")
I have confirmed that:
1) DS_Grades has the right PupilIds
2) There are actually values in the Grades field
3) Both PupilID fields (I.E. in both datasets) are definitely Integers and not text.
Moreover, if I add a calculated field to DS_Grades called "test" and populated with the value 208301, which is a valid PupilID, then I can enter the below formula and it works fine:
=LookUp(208301, Fields!test.Value, Fields!Grade.Value, "DS_Grades")
So, the LookUp itself must be matching properly, which means that the PupilID fields must be causing the problem, but I have quintuple freaking checked them and they definitely have the right values, in the right format. I am at a total loss as to why SSRS thinks that they don't match.
Help please!
Got it! Some filtering was at Dataset Level (instead of query where I normally do it) that was throwing the whole thing out of joint. Removed that, and it's fine.
I have the details of my report being summed up in a summary expression, all works fine. The fields are decimal values of hours worked. Thus, the summary value is also a decimal value. I'd like to access the summary value and convert it to hours / minutes. I've labeled the express as "WorkTimeSum", but can't seem to get a handle to it, however. Fields! obviously won't work since it is a summary expression. I was thinking ReportItems! should work, but to no avail. How can I use this expression field (in a summary row) in an expression in the same summary row?
If I've understood correctly, you're asking how to reference the textbox containing the total work hours value so that you can convert it to hours and minutes using an expression in a different textbox?
You can use either ReportItems! e.g.
=ReportItems!Textbox20.Value)
or ReportItems("") e.g.
=ReportItems("Textbox20").Value
to reference the value of another textbox. Be careful with the names as they are case sensitive.
You can use aggregate functions in any expression. For example, in any header rows you can use the following expression to determine the total hours value:
=Floor(Sum(Fields!hours.Value))
Sum(Fields!hours.Value) is just the total hours in whatever context, e.g. the group total if it's a group header row; you can use this expression as an input in any other expression you require.
It sounds like your issue wasn't the conversion itself, so hopefully this points you in the right direction. If you need further information please specify.
