I need help to make this excellent add-on to work on my cart.

I have been trying for days to make it work, read many postings and still cannot figure out how to make it work.

As soon as I upload the intall script, it breaks. When I click the picture on the product details page, a new page loads with only the picture on it. If I uninstall the script, the cart goes back to the pop up menu for the product detail pic.

I should mentioned I am running a "store-bought" template (Afterwards I came to find out they are very difficult to modify)

I know I am installing it right, since I was able to make it work on a brand new db with a classic tempate that come with zencart. It looks beutiful! now I want that on my template.

I think a file is overwriting the javascript for lightbox. When this file is uploaded (tpl_modules_main_product_image.php) I get the image in a new page as describe above.

I have a slideshow running on the banner, I think it uses Javascript, could that be the suspect? if so how can I fix it.

I am sure now something is overwriting it. If I switch back to the classic template, lightbox works! without changing anything, I switch to the purchase template and it doesn't work (only regular pop-up window).

I need to finish this site asap, any help will be greatly appreciated!

Here is a link to the demo site:
