Intended function: require user to
select an option from the drop down menu. After user clicks submit button, validate if an option is selected. Display error message and not submit the form if user fails to
select. Otherwise submit the form.
Problem: After
select an option, button has to be clicked twice to submit the form. I have no clue at all..
