My forum is centered (document margin right and left set to auto) like this site here.
I have the ebay ad code below inserted in the "Below Navbar" ad space.
What happens is that it pushes the whole forum all the way to the left of my page and I can't figure out why.

It's weird because their flash ads I have no problem with, only the html ads.
If this part of the code below &format=Html is changed to &format=Flash it works fine. (But shows a different ad which I do not want)

Any help on figuring out why this is happening would be great, thanks!
