Update cart button and the remove items button don't work

I have only one product on my site, its a test product, and
I want to make sure everything is working before adding products.
When I add the product to the cart and then view the cart and try
to update the quantity, nothing happens. Same problem when I try
to remove the item from the cart.

Thanks for your help.
