When I try to change a field in my form I get an error that says,"Update or Cancel Update without add new or edit".
Based on what model you pick from the combo box,depends on what information is displayed. When I try to check one of the fields I get an error message.
This is the code that is in the unbound combo box:
SearchForRecord First, ="[Model] = " & "'" & [Screen].[ActiveControl] & "'"
Attached is the form and table.
