Hi Jason,
Thank you for your reply.
Here is the link for the site;
shop_01_rig.php
(This is just one of many pages with the same problem - please make sure you test it on FireFox4.01 - the latest one. There should be a button right above the product list saying "view order", which is the link not working.)
I've attached the PHP file for this page.
Looking forward to hearing from you!
Thanks,
Rika
