Update:
I kept making the percentage smaller, down to 45%. Revised the item, still shows wide with horizontal scrolling on the Ebay preview of the template.It also shows the nav bar fully. However, when the changes are saved, this is the result you get:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8920858829
Does anyone have any ideas as to how I can make this work> I also removed frames, because I really don't like that blue, it has nothing ot do with my color scheme.
Thanks again!
