script not loading in content area?

Hi, i made a content area called "Ads" and put a single ad banner so it would display on the Product Results page, it worked fine, client now wants rotating banners, and thats not an option with the gallery... so i downloaded "Easy Rotator" ... made the rotating banner and put the script into the "Source code" part of the content section.

It doesn't load when you click a category, just shows the white space, but if you click on a detail image and then click on the "back to catalog" link, it shows up....

any idea how i fix that?

next version can you add a "rotating" banner function w/ links to the gallery options :)

the site is limerockparkstore.com/index.php


Thanks for any help that can be given! I need it!
