problem with ebay partner ads

i’m having a problem using the ebay partner program ads on my site https://mustangtraderonline.com. It breaks a bunch of different things, like tabs, add to favorites, image gallery, etc. when i use their coding.. right now it in on the home page and breaks the tabs for ‘featured’ and ‘random’ – nitiher work.. anybody else have experience with this. i used the parameter around their coding - didn't work.. i used a new <div> around their coding - still didn't work.
