OK, Downloaded and installed USPS shipping methods this morning. Tried several different settings and I get this message on checkout
"United States Postal Service
(1 pkg, 8.00 lbs total)
"An error occured with the USPS shipping calculations.
If you would like to use USPS as your shipping method, please contact the store owner."
Would I have something set incorrectly in the module options, The only thing I am looking for is Priority Mail (Domestic) and Priority Mail (International).
To be perfectly honest I use USPS Prices as a general shipping quote.
Currently using OSC V2.3
