PHP Filemaker Javascript

I have a Filemaker Database with PHP pages built. I need someone who can correct the variables so that the forms post/get and link together while passing information. I also need some Portal records displayed. Last, I have some basic javascipt that i need on the 'menu' page which will keep a running total of qty fields AND display the items selected in the right hand frame of our cart. You can see the site at: [login to view URL] The logic is correct, however the php is not passing, getting or pushing data in the db properly.
