Add to Cart button won't work

I have my website set up and VirtueMart configured, but when I test, nothing happens when I click on Add To Cart. My website is www.boostrules.com .
Thanks for your help

Please install template using HotStart installation method.

I reinstalled the whole program using the hot installation instructions. The shopping cart works with the sample products, but as soon as I put on a test product of my own, the add to cart won't work for that product as well as the ones that worked before I added my product.

Perhaps it's not possible to add any product into the cart. Did you install any additional component or module after HotStart.
