Hi Everyone, I downloaded the sample code to request a rate from fedex's website... i placed the WSDL file in the proper location, I have my acct number, password, meter number, and key. When I run the script I get this error:

Error in processing transaction.
ERROR
prof
1000
Authentication Failed

The script they give is as follows, and yes i do actually replace the XXX and YYY everywhere it says.:

I am not quite sure why it isn't working, i've read about using a proxy, but I am not quite sure how i would use it in this case? Isn't the point of using SOAP and WSDL to avoid using CURL, Direct Connect type stuff?
