DriverTypeCombo.Column(2)

Are you referencing the correct column? Column 2 would be the third column in the Combo Box.

Use 0 to refer to the first column, 1 to refer to the second column

Thanks Kevin, I changed the reference to the column.  AND I did change the me.filter to me.filteron  
I sent a msgbox to test the values and the references are now working.   But when I run it, I get a run-time error '3709' that said, "The search key was not found in any record."  
I changed my code to read:      
Me.Filter = "DriverTypeCombo.Column(1) = """ & DriverTypeFilter.Column(1) & """"
Me.FilterOn = True

If I substitute the me.filter to read:  Me.Filter = "Substitute", I get an error message that says enter parameter value for Substitute.

It's just not recognizing the DriverTypeCombo or DriverTypeCombo.Column(1) as a search parameter.  I will get the values if I msgbox them.  The code I used that worked was referencing the recordsource of teh drivertypecombo, i.e. drivertypeT.

    Me.Filter = "DriverTypeID = " & DriverTypeFilter.Column(0) & ""

Thanks to all who helped out!

What's DriverTypeFilter?

Alex, that is the name of the combo box I'm using to filter which type of (bus) driver I want such as regular, substitute, trainee, etc. see photo above.

Oh just a thought is the record dirty when you try to filter?

What's the difference between DriverTypeCombo and DriverTypeFilter?
