I'm working on creating a webstore using zen cart. As I'm developing I'm choosing to work on it using my iMac and MAMP before I decide to upload it to my server. I just installed the google checkout module, and I'm trying to make it to where you can only checkout with google. I even did the little trick to hide the other "check out" button or whatever.

Anyway, I can add stuff to the cart (i only have 1 item on the store for testing right now). But when I checkout with sandbox it says "Oops, we can't process your request at this time."

Then I go into the integration console and I see the following error:

"Carrier calculated shipping options have not been provided. Must specify the carrier and delivery type."

The only shipping module I have turned on is USPS. And I have a web tools ID.
