Oscommerce Simple Template Structure problem

I have a problem (Java Script Error) with my online shop. It is built using oscommerce with the Simple Template Structure contribution added on. My site did work. But I recently redesigned the template and now my product pop up images dont work. However when I upload the old template the pop ups work again and I cant work out what is wrong. The templates are basic html. I have tried removing anything complicated like the css and small bit of java script to add to favourites and uploading again but this makes no difference the pop ups still dont work. So I am out of ideas. I have uploaded my two templates, the old one that does work and the new one that causes the java script error.
