I tried that and it doesn't work. I also tried eliminating the display SESSION_Final and using the cartQty output, that also does not work and eliminates the (0) when the cart is empty. When I tried putting the session start in the count.php file and adding that to all my scripts, my index page fills up with lines and lines of errors.
The other thing is, the cart total, quantity etc is displayed in the r_container, so technically it has nothing do with the cart page, product page, index page. The right container always loads on its own, doesn't matter which page is loading. You would think the product page and r_container do not interact with each other when loaded, but "technically" they are loading and interacting with each other.
I have tried so many combinations now, I loose count. The closest I came was when the product page loaded, the cart displayed errors pertaining to the r_container script. So they can load together and also interact separately.
As for the enlarge image as you suggested, yes it is a wonderful idea and when you are on the product page, you may have noticed a giant ugly button under the image. That is to remind me that I want to do a mouse over - enlarge image with perhaps another image or two under in little thumbnails. That in my opinion will be tricky to get each "id" to load two or three pictures each and then using JS or Jquery allowing them to double size/enlarge on mouse over.
I have learned in this last month that if I jump all over the place and try to work on too many things at once that my head explodes so I have to one thing at a time now. (search bar script,payment system,getting the buttons to change also on mouse over[JS form issues are keeping me back!], shipping total set to minimum rate and also displayed in cart, shipping calculations for total weight added onto total). -I have some work cut out for me and I made it this far, no turning back now!!
