Nice hack and I hope you can help with the install on my site. I've ran into a couple problems with trying to install. I've installed everything as instructed but I'm getting this on my site:
http://www.muscle-mustangs.com/shop/product.php?productid=16199&cat=285&page=1#tabs
It deleated the entire product description and when the tabs are clicked, they don't bring up the desitred function.
Anythoughts to what I have done wrong?
