I am the queen of ebay if i do say so myselft, i have created over 76+ listing templates and storefronts. I can take your code and install it on auctiva with no problem, i can fix your code as well if its broke. The problem with most designers is they dont code for ebay, they dont understand that its another animal.
All i would need from you is your auctiva user and pass and thats it. oh and of course the code.
Please feel free to check out my ratiing here, on ebay "designedbyjackie" and just google my name :)
