I have a form using jQuery validation. The form displays an error message for each required <input> if the user hasn't filled it out. For the <select> items, the form validates, but it doesn't display an error message if the user hasn't selected an item from the from the dropdown. Can you write a rule that would display a message for the two form selects in my form. See attached code. I just want the message to say something like "Please select an item".
