I am new to Zencart, and working with installing the USPS mode, I think I got it install right.
- /includes/modules/shipping/usps.php
- /includes/languages/english/modules/shipping/usps.php
- /includes/templates/template_default/images/icons/shipping_usps.gif

have it in test mode. I added a couple things to my cart, but when I go to my cart. Nothing is showing for USPS. It's like the Mod is not there or not working HELP

Any help would be appreciated.
