Thank You. Just grasping at straws at this point.
FedEx is getting the Rate Requests, however they say that the requests are missing information they need to process it correctly.
I asked if they could give me what's missing?
They said; "Too many things to mention, just have your developer contact us at this case. # 33253285"
I abandoned their testing URL and set-up the 'live' or 'production' url, as they call it and have trashed the files, as you asked.
