Hi Scott,
Glad to hear you got it working and you solved the problem with why you had a "double template". The category thing you are speaking of is an eBay problem, I have notice that when I am previewing many people's listings at ebay using IE, that half of the time their categories do not show up yet the space where they would go takes a bite out of the display area anyways. Just thought you would like to know this for future reference. Best of luck with your listings.
