Jason Feed back to you on my solution
Jason thanks for the help!
I went throught the whole PayPal Sandbox Manual it was of litlle if no help, some tips but all in all it did not teach me anything I had not discovered.
The soulution ended up with me switching from PayPal Standard to PayPal Express, I did use a different test user ID, as I had a feeling the one I was using might had problems, this I found was true, why I do not know. I then switched back to PayPal standard after the sucessful test in PayPal Express to see if in fact it was the user ID that was the issue, it was not, PayPal standard would not give me a valid test and I would get the same login in ID error, so I went back to PayPal Express and I got a functional good test of the payment gateway, it does not make sense, but I have a fuctional payment gateway that does test good.
I do think however for Power Store 4 that your company needs to produce a instructional video on working with the payment gateway in PayPal Sandbox, you have it for everything else. I look at it this way if this part of the store does not work right the store does not go on line, and I was not about to put the store on line till I got a good fuctional test from the sandbox to verify the payment gateway was working, if you are worth your salt in this business that is what you do proper QA, so I think a Video on the Sandbox is now manditory from your company. please pass this message up the line for me.
Thanks again for you help,
