On the submit, the userdepartment dropdown selected index always equals -1 I have tried alot of things but I can't get it to work. See code Below. Dropdowns have been giving me more trouble then I ever thought that they would. Anyone help me out with some common mistakes that I might be making time and time again? If I can't get it work, would you suggest that I get it's clientID and just try to get it's value from the forms collection? I'm going nuts over here. Thanks.
