Nevermind
We have talked with the client and he in not interested in calculating on an item by item basis anymore. We are having much more serious problems now with the checkout process.
When My assistant uses PayPal to checkout, it works for her, but when I do it through PayPal it goes to checkout failure page or your cart is empty page.
We also tried to implement the script you gave us for shipping options via air, ground express etc. Once we implemented the script it said :
missing - illegal service - code
We have since changed the script back to where it was before the shipping options. You can see it at order.php
