This is why you should be referencing the first Column, which is the default.
Then there is no problem.
;-)
Forms!FormName!ListBoxName
For example you have a combobox of Customers.
The first Column is CustID, the second is CustName, the third is CustEmail
This CustID column is the field you should be referencing.
Then the listbox can easily be used to filter for the selected CustID.
The query can be used to pull in any other fields you need.
Either that, or change the rowsource of the Listbox so that the field you want is the first column.
These are interchangeable:
Forms!YourForm!YourListBox
Forms!YourForm!YourListBox
Forms!YourForm!YourListBox
Finally you can reference a column other that 1, but it requires a bit more work.
Something "Roughly" like this:
Create a Public variable in code:
Public lngpubCustID as long
Then set it equal to your combobox column:
Sub YourListBox_AfterUpdate()
lngpubCustID =me.YourListbox.Column(n)
...
end sub
... and retrieve it with a Public function
Public Function GetCustID()
GetCustID=lngpubCustID
End Function
...then use the Public Function as the Query criteria
WHERE YourField=GetCustID()

Just to clarify, the column needn't be the first column to avoid referencing it.
Merely the bound column.
So if you've set the bound column of your combo control to be, say, 2 then you can reference the column as you would have with Forms!YourForm!YourListBox
A hidden textbox is another option as mentioned. It might feel redundant to you, maintaining this control for just that purpose, but it's fairly common. (Expressions don't resolve immediately though through the UI - you might want to assign the value in code).
Other than that, as has also been mentioned, a function call is normal.
However this needn't be a user defined function.
You can deceptively maintain the expression you were using and let the Access expression resolve...
i.e. instead of
WHERE Somefield = Forms!FormName!ListBoxName
which would fail, consider
WHERE Somefield = Eval("Forms!FormName!ListB
wh
