I followed your instructions but have a few questions. I wasn't able to get it working, and now when I go through the checkout process there's no shipping calculated. When you said to "create a hidden form element of the same name, and set it to capture the value posted from the checkout page" and then gave me the code to put into the page, does that php string in the code capture the value or did I need to do something extra.
Also, in a help session with jason he mentioned that eCart has some problems when you edit it. Do I need to go download any kind of fix? Right now I have USPS Shipping, FedEx Shipping, UPS Shipping, and then the two options Local Delivery and UPS Second Day Air as rules in the shipping tab of the eCart Object. Please tell me if this is wrong.
I've attached confirm and checkout pages just in case. Thanks for your time..
