I'm new to osCommerce (v2.3.1) and I'm trying to install my USPS module to give shipping rates for USPS Parcel Post shipments. I assume this is possible? Does it use tables or something or does the weight come from a product description and if so, where do I define this? I see no weight properties in catalog items of the sample osCommerce shop.
Right now I have USPS module installed with my USPS user ID (and password) entered as well as my zip code in the Configuration > Shipping/Packaging section. Firefox isn't letting me sign in as a customer but Internet Explorer is and tells me:
An error occured with the USPS shipping calculations.
If you prefer to use USPS as your shipping method, please contact the store owner.
Thanks in advance for any help!
