I've got a quick Access database update I need to do and it's been years since I've touched Access. What I need to do is take a text box, and have it pre load with two values from another form. So far I've tried just adding them from the controls menu and I get nothing but errors. In the data menu on the property sheet, I edit the control source and put the following:
= «Expr» Forms![AFR]![SerialNo]
so I'm trying to load the SerialNo field value from the form AFR. But I get the error message "The expression you entered contains invalid syntax. You may have entered an operand without an operator."
Any ideas what I'm doing wrong?
The problem is that Access has tried to be helpful, and entered the "" in for you which is not needed. You should use this instead, probably as the default value:
=[Forms]![AFR]![SerialNo]
Note that if form AFR is not open when the second form is opened, then you will get an error of "#Name?".

I've an Access Form with few combo and text boxes. I'm calling information in some text boxes from access tables after selecting value from one of the Combo box. Values are coming correctly but I also need to replace the old information with new one and update the same table again with new information. I tried many VBA codes but Access is giving me error "Reserved Field" every time and close the form automatically.
Can someone please help me here? Let me know what more information you need from my end. I'll be grateful to you. Thank you
With out seeing specifically what you are trying to do it is difficult to be sure what you need. What I think you want is to update the test boxes and the desired table fields based on a combo box selection.
If that is your desire you need to bound the text boxes as suggested. Then the VBA code would update the value property of the text box:
if me.controls("comboboxname").value = "a" then
me.controls("textboxname").value = "A"
Else
if... (etc etc)
Or instead of nested ifs you could use case.
Once the form was closed or the record changed the tables would be updated.
I'm trying to populate a control from an external form with a string value on button click - this is working perfectly when there is already existing text, however if there is nothing then it is treated as a null value and therefore returns a Type Mismatch error.
I thought I would be able to work around this by using:
Nz(Forms!frmSpecifications!boxScratchpad.value, "") = "Text string"
But this hasn't worked.
Could it be to do with how I am calling the control, or the properties of the control itself?
UPDATE: After looking into this a bit more I have pinpointed the issue to a SQL query execution earlier in the code which runs an update statement on the same table that boxScratchpad normally gets its data from (although the field which is fed into boxScratchpad is not actually updated). If I comment out this code so that the update statement doesn't run, boxScratchpad populates successfully. It seems like there could be a conflict between the table being updated and boxScratchpad being assigned a new value within the same code?
First of all, understand what you are trying to accomplish and what your code does.
Assuming your control is a textbox, the property that displays its text is value. If your control is a button, the property that displays text is caption.
You are trying to assign a string to this control value or caption, there will be no issues if those properties are currently NULL.
The mistake lies within the nz. If nz evaluates your control's property to NULL, it will return your empty string as the answer, thus ending in this situation:
"" = "Some text"
Which will throw error "It requires an object".
Remove the nz function.
To really test the interference of your SQL update with the control, use the inmediate window in vba editor to execute and test your code.
I have 2 bugs beginning to show up in my app, both in subforms. New text boxes, labels and check boxes will only display in design view.
Bigger problem: I can add a check box by dragging it from the field list but get the error 'Control can't be edited; it's bound to an unknown field [FieldName]' when I attempt to click it in form view.
I can edit the value directly in the table and I can edit the value in the form's underlying query as well.
I've tried decompiling/recompiling and importing all my objects into a new database. I tried using a different machine to see if there was something wrong on mine. nada
This is an existing application with hundreds of man hours into it. I can't just start from scratch.
I was getting this - It took me a while to realize because the error statement only persisted while data list item was click-depressed. It turns out in my case that somehow a number of spaces existed in the Control Source property. I found this when I entered the table name in the field and the error statement switched from Control can't be edited; it's bound to an unknown field '(bunch of spaces) ' to Control can't be edited; it's bound to an unknown field [tableName]. After deleting the [tablename] and ensuring no spaces in Control Source, the combobox toggled to 'unbound' and there was peace in the valley.
I had a similar problem. After many hours of work I discovered that all of a sudden I had to add the table name to the Control Source property.
Go to the properties for the control and add the table name i.e. tbl_MyTable.MyField.
I have no idea why Access sees an ambiguity problem all of a sudden for just that one field but that was obviously the case.
I had this problem and tried adding the table name to no avail. On the load event of the form, I changed the recordset (same table but filtered using what is passed by me.openargs instead of on the docmd.openform command due to needing the id passed for other things to work) in VBA. I thought that once you set the form to the recordset, you were done and could close the recordset. Not so, leave the recordset open until you actually leave the form or this error will occur.
Change the control source from "=[Some_Value_in_Table]" to [Some_Value_in_Table]. To be more precise remove the equal to sign.
I tried all these things - to no avail. I had a few fields bound and only one of them was causing grief - the others were fine. I swapped the Control Source around between controls to isolate the issue - it was definitely only related to the field somehow - after refreshing external links, removing and re-adding the offending field from the Access query opening and closing the offending form - everything somehow fell into place - I can't say exactly what fixed the problem - but my life can now return to normal! In a nutshell - these are the steps I followed:
* refresh links to external table
* remove and re-add fields in query
* confirm the the field is editable at the query level
* copy and paste the table.fieldName from the query's sql statement
* save - close query
* paste into the Control Source
* save and close form!
Good luck!
I have been battling with this problem for weeks now and simply cannot find a solution.
I am using MS Access 2007
I have a table caled "Policy Information" where all of my data is stored. I have created a combox box to autofill a few text fields using a query called "BC Allocation Query". By choosing from the combox269 field I created then 6 other text fields are automatically completed. I used the function =[Combo269].column in the control field of the text field I want auto-completed.
This all works great however I cannot seem to relfect the information from the text boxes which are auto-completed to relfect in my Access Reports whcih I have set up.
Please can someone assist me withthis before I jump off a cliff:)
Are these text fields on the form bound to fields in the source for the form? If not, they are unbound, and you need to write code to save this information into the table when you navigate away from the record or close the form. If they are bound, you need to programmatically force a save of the record when VBA changes values, otherwise - you might get the dreaded 'values changed by another user' verbage in an error.
I'm trying to display the sum of a field in a text box in the form footer. The field is not calculated in any way.
Here are a couple of the things I've tried:
=Sum([txtWeldInches])
=Sum([WeldInches])
=Sum(CDbl([txtWeldInches]))
=Sum(CDbl([WeldInches]))
...well you get the idea. Each iteration I've used results in the Text Box displaying #Error Without exception.
I've used similar constructs in different forms in the same project, so I'm not sure what the problem might be.
Has anyone run into this before?
EDIT:
I ended up writing a VBA routine to update the boxes when it was likely that they would be changed rather than trying to get a bound sum() function to work.

All of the domain functions are based on the same query (over the underlying recordset). If one of the bound functions on the form has a binding error, all of the functions on the form will return an error.
In other words, make sure all your footer controls are resolving properly and not hitting any nulls.
If you use a SUM or AVG then make sure you are also using the Nz function:
ControlSource = =SUM(NZ([FIELD],0))
Is the field "WeldInches" existing in the data source for this form?
What datatype the field "WeldInches" is?
EDIT: I have looked at all your comments. If it doesn't work by databinding, try and use the unbounded way. At runtime, get the value of WeldInches using DSUM and set the footer textbox's value when the form loads.
Also, remember to update it at places where you think the SUM could change.
I had the same problem as Rister.
The source of the form was an underlying query.
I had a bound text box named txtQty on this form. Its control source was Qty (based on the underlying query of the form).
I created an unbound text box and entered =SUM([txtQty]) and received an error.
I tried various ways to find a solution and was very desperate.
Then I deleted the underlying query and created a new one using the same name and fields as before.
Then I entered =SUM([Qty]) into the unbound text box on the form and voila, it worked. Note that I didn't enter the name of the bound text box (txtQty) into the expression, but its control source (Qty). I don't know why, but it worked for me.
I know you said "Form" but for those who have issues with the Sum formula in an Access "Report" the formula has to be in the Report Footer NOT the Page footer. Took me a while to figure it out as Access defaults to only showing the page footer.
You want to sum by the name of the column in the record source: SUM([WeldInches])
Make sure there are no other textboxes with the name WeldInches.
