Hi, when I select the option of the product the phrase "add to cart" disapperad.

Can u fix this problem?

Also another question: is it possible to make all of the product page similar to the one "Veli Celing Wall"?

Or I have to do all the modify for each product? (I mean the header, the margin between the header and the body -- those one are just fixed)

Tell me if it's all clear.

Thanks
