Four days since my first install and I am still trying to tweak this Zen Cart. Big learning curve with php.

I also purchased the ebook to resolve this issue but they don't discuss U.S.P.S. Shipping Module.

I am selling 1 product which has 5 attributes. (Indiv pack, 1/2 case, 1 case, 5 lbs and 10lbs). The indiv pack weighs 2lbs.

I have tried to add the basic weight to the product of 2lbs and I've tried to add weight to the individual attributes.

When both the product and attribute weight is left at 0, the USPS calculator works and gives me the following:

Available Shipping Methods Rates
United States Postal Service (0.10lbs) (Priority Mail (2 - 3 days)) $4.80

When either the product or the attribute or both are annotated with a weight, I receive this:

Available Shipping Methods Rates
United States Postal Service (0.00lbs) (Priority Mail (2 - 3 days)) $0.00

I have searched though the FAQs, Tutorials, ebook, and Forum and cannot find an answer to my dilemma.

Will anyone help?
