Project Description:
I need a pop-up or a generic script that will run code, which contain anything that I want, including a pop-up, when the users exits the page. I have to be able to add conditions to the script. For example, if I only want the pop-up to appear if a certain cookie has been set when they attempt to exit the page, I need to be able to define that condition using PHP.

100% escrow provided if requested in your bid.

Thanks, and good luck.
