One option is, in you code that uses the value from the combobox, to have a check for Null:
If IsNull(Me!YourCombobox.Val
' Wrong or no entry.
MsgBox "Select an option."
Else
' Continue.
' Run your present code.
End If

If IsNull(Me!YourCombobox.Val
' Wrong or no entry.
MsgBox "Select an option."
Else
' Continue.
' Run your present code.
End If
/gustav
