I am a new user to Zen Cart and I am having difficulties getting the USPS shipping model to work. I have everything set up thru the Post Office as well as the Shipping Model set up. When I go to the site to est. the shipping cost it produces no data after entering in a country, state and zip.
I have not loaded any plug-ins and I am wondering if that may be the problem. I have seen these and been reading up on the forum but I am not very familar with the lingo everyone is using. Is there an easy way of explaing to a non-programer how to get the USPS module to work correctly?
