HI Jon,
Thanks for the reply.
Here is the url for the page where the button should appear.
http://1090495.nwinetworks.com/xcart/product.php?productid=33&cat=15&page=1
You can see the does not exist message is there.
* This page is on a closed test server. I think you should be ale to get on with the URL I have posted above but if it you get asked to log in let me know and I will private message you the password info
Thanks for looking at this
Scott
