Item amounts will not update

I have numerous items im trying to get updated on my product.

For example a person will get a basic computer system, if they want to add an extra item they select it an it updates the price. But it isnt working as it should be.

My website address for the exact product problem is http://www.computerwormsliverpool.com/for-sale/product/view/57/32
