usps just not working

usps is not working here on my site https://www.nonniescollectables.com

it is saying:

i have called and had it moved to production servers, i have verified that the rate calculator is enabled, i have searvhed the forums, and i put my address in the order so i know it is a good adress, and still nothing.

after i had them put me on the production server, they sent me an email with production urls. isnt that already in zencart, where it asks you what server you are using, production or test?

i am fumbled

here is what i have in admin:
**
Enable USPS Shipping
Do you want to offer USPS shipping?**
true

Enter the USPS Web Tools User ID
Enter the USPS USERID assigned to you for Rate Quotes/ShippingAPI.

that is just the regular webtools user id right? do i have to sign up for anything else?

Which server to use
An account at USPS is needed to use the Production server

this is where i thought the production urls are automatically being used...
it is set tp production

I had the same problem (yellow) and fixed it the same way (removing US as the zone). I also only ship to the U.S., and FWIW, I haven't had any orders from outside the U.S. since changing the zone a few months ago. I also don't have any International shipping options available.
