Thanks Darius for the quick help! Everything works except the form is eventually submitted and the message goes away without the user clicking it. The problem is probably with the event.preventDefault(); function.
I tried the following with the same results... event.stopPropagation(); and return false; Do you have any suggestions? I've tried it with Firefox 7.0.1 and got the above behavior. With IE9, it waits for the user to click "OK" and acknowledge the message before submitting the form.

Is there a way to trigger a Javascript when the submit button is clicked, before the form is accepted? To be more specific, I need to require the hospital discharge status field to be filled out if the form has a discharge date. If the discharge date is set, but the discharge status is empty I want to give an error message and not accept the form. I can't simply set the field as required because the form is only partially filled out at the time of admission. The discharge date and discharge status are not known at that time.
