virtuemart override

hi, i have a problem with my website. I'm using Quark template in http://materassodelbenessere.com/ and i have installed Vm3 for shopping, using the css of Storefront template. It's works until i click on cart, where the template's css are of quark and not more of Storefront. You can see that on http://materassodelbenessere.com/index.php/shopping clicking on add to cart > show cart. How can i resolve this? Thanks for the helping.

Hi

Please try add a nem menu item leading to cart, so cart will get an Itemid and You will be able to attach a template to it than.
