I cannot find the information on how to set up my shipping calculator to reflect actual shipping costs. On the checkout page, there is a box for my customers to add their zip codes so that shipping can be calculated, and so it seems that this option would be possible-- but I can find no information in the pages and pages of how-to instructions I've been scouring to set up the shipping calculator to automatically figure the shipping charges according to the location of the buyer. Can anyone point me in the right direction to find instructions on how to do this? FROM THE PAYPAL INTEGRATION HOW-TO INSTRUCTIONS: ***PayPal displays a shopping cart page, which lets buyers review their selections, specify quantities, and remove items before proceeding to check out. If you have set up shipping rates in your account profile, a shipping calculator displays at the bottom of the cart. When the buyers enter their zip codes, the shipping amount is calculated and is added to the total. If your account has sales tax associated with that zip code, the tax amount is also calculated and added to the total. If the buyer changes the zip code, the shipping and tax amounts are recalculated.***
