Hello wjoycem -
Yes - there are any of a number of things that would be considered active content - this can be an issue especially if you copy/paste content into listings from an external source - that often brings the related code from that source into the listing and may contain Javascript or other active elements.
there are tools available where you can review your listings for active content on eBay.
One of the better ones is: HERE
as it will show the elements of the HTML that are affected. However, if you are not familiar with HTML and Javascript (it is the Javascript that is typically problematic) the results may not mean much to you. However, I am not aware of a tool that will review all of your eBay listings and let you know the ones affected at this time.
Please also keep in mind that eBay is not even going to begin blocking active content in listings until June and we are working towards updating active listings for our customers with regards to the gallery and the counters and will soon have new templates available. Newly created listings on Auctiva and then posted are already using the new gallery and counter (if enabled).
