I ttried editing my post right away and it would not stick. change this line:
MyVar = "C:\Folder1\Folder2" & CustomerID
...to...
MyVar = "C:\Folder1\Folder2" & CustomerID
This probably runs pretty slow with all of those Domain functions. If the RowSource of the ComboBox is "tblDropROI" there is a much faster way to get the values. If "OrgID" is a number then your code should be: "[OrgID] = " & Me.OrgID )
