Sorry, we can't provide any support for third party software like zen cart, because there are hundred of thousand of third party scripts out there just for php.viewtopic.php?f=16&t=50665
I don't know zen cart myself.
Please ask your question about zen cart at their own support forumhttp://www.zen-cart.com/forum.php
They can provide much better and efficient support for their own product then we can.
