Pop Ups Not Working

A contractor recently modified the look-and-feel of our web site. Since that time, the pop ups on our home and interior pages haven't been appearing. There used to be two pop ups that would appear once a day per visitor: one that would ask them to sign up to our newsletter and a second that would promote our ebook. Now, neither appear. I'd like the newsletter one to pop up 0-5 seconds after they come to the page (5 seconds would be preferable) and the ebook one to appear when they leave the page. I believe that's how they worked before. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform NT web server
