I have a form on a php page, and all i simply want is when a user clicks "submit" it brings up a PopUp message / error.
I have gone through the site and for some reason have not found a simple solution.

Are you sure you want to continue?
if "Yes" .... go to this page
if "No" .... close the popup and return to the same page
