Shopping Cart Newbie Problem

Hey all, I've been using php for my first php project, it was going ok till I got to coding the shopping cart.

Specifically the quantities doesn't quite work, although I made some progress with it. When I add an item to the cart a quantity of 1 is passed to it along with the product ID, this works fine. Although when you want to change the quantity and you change it to 3 and press return it works, press the button to submit the form and it multiplies the product ID by the value of the product. Adding more than one item also creates similar problems.

Basically it doesn't look like I've grasped arrays and sessions here.

The code for the viewing the cart is here: http://www.hostmaster-x.co.uk/shoppingcart...tityproblem.txt

The cart with the problems outlined go to http://www.hostmaster-x.co.uk/Products.php


If anyone can help me with this I'd really appreciate it - I'm pretty lost here


Cheers,

Graeme

You need to comment your code. We can't guess where some variables come from and why they do.
