I'm working on getting a new site going. I'm very new to Zen Cart. I had a test cart on my domain and the buy now image would get replaced with sold out when someone put a hat in their cart (hats are one of a kind, so stock is set to 1, max order set to 1).

On trying to get the real store to work, I can't get the sold out image to show up. I've searched and search the forums and FAQ's and can't find what I am looking for.

Demo store is: www.donnetta.com/cart

new store (sold out not working) is: www.mybabyhats.com/catalog

Any help would be greatly appreciated.
