Displaying 'Add to Cart' button on New Products and Featured Products

Hi all, I have a display of new products and featured products and I wish to add an Add to Cart button. Now I have toggled the option within admin panel of Zen Cart and it does not displayed. So I'm more interested in find the actual php file and placing the code in myself, however I cannot find which file it is. Here is my site http://www.you-vebeenframed.co.uk/

These two areas are designed more as a "tease" than an operational portion. In order to do what you are thinking of, you would need to do a great amount of coding UNLESS you had NO products with attributes.

BTW - You only need one gift cert with a price of $1.00 and let the customer purchase any number they want. That way, you give the customer the option to get as close to the price of an item as possible.
