Still need clarification
Jason, I think we're getting close, but you still haven't verified if I should be using the PayPal API user name, API password and API signature OR the paypal email address, password and API signature?
I have not been using sandbox.
I think it's key you tell me whether to use the API user name or my paypal email address I use to login.
P.S. It's interesting to note I've tried them both, made them the same, uploaded the files, and when I later open the Checkout Payer Provile it has somehow changed my normal paypal password to the API password. And another time it changed my email address to my API user name.
