Website editing and Form improvement

Job Description

We want to change the way a form on our website works. On http://www.curadebt.com/signup/defaultexample.asp, if you don't fill in a obligatory field, there is a pop-up that shows asking you to fill in the information and you must click ok to get rid of this pop-up. We want it so that if the user clicks anywhere on the page, the pop-up disappears. We will want to be able to replicate this on various different forms on the site, so the change to code must be clear and well explained.
