PHP PROGRAMMING HELP ON ECOMMERCE PROPRIETARY SOFTWARE

We have updated a website to the latest version of an ecommerce software - which is sold at www.ecommercetemplates.com. We have a live shop running, but at this time we have copied this over to a temporary domain, copied the database and updated it all. Everything except a couple of items seems to be working fine. The couple of items that we need fixing by a gun php guru is this: 1.) There is an argument issue on the products page:(please see attached pdf) 2.) The email javascript does not popup or work. If there is anyone who thinks they can fix this and maybe have some experience with this software that would great. We have a general idea of it, and the layout. There is also a support forum for the software,however we have already tried there with limited success. Hope someone can help. thank you.
