javascript conflict?

I am trying to get a product comparison function for Virtuemart to work on a new site. It works fine with templates from other companies, but there seems to be some conflict with the Gavick ones.

If you click on the tick boxes by each product and then click on "Compare Now" you should see a page comparing those products.

In IE I can check for problems and they tell me "Object does not support this property or method". But it doesn't work in any browser.

The developer of the comparison feature thought the gk.js had some conflict.

If I switch to a template from Shape5, the problem goes away and the comparison functions as it should. There must be a conflict with something and javascript seems logical.

I would really appreciate your help.

Thanks,
Elias

Looks like conflict between mootools library and jQuery, please try to use noConflic() command in this extension script source file.
