I have that field automatically dropping down when I enter it if it is blank so if I tab to that field the drop-down opens and then if I tab off without selecting a value my code above thinks there is a value (the first item on my drop-down list) and the validating doesn't work the way I need it to and when it leaves the field it is blank because no value was really choosen.
