Thanks Jason,
The real site already has Express setup and working pretty well. But now it needs to be changed to use Advanced because they offered the site owner a better rate through that gateway.
Thanks for pointing out the document. I had not seen that one.
I think part of the problem is PayPal's naming. PayPal Payflow, Payflow Pro, PayPal Advanced (which uses Payflow gateway or Payflow Link) and is also called Payments Advanced. They are clearly different if they don't work the same so why in the world would they name them all Payflow? Their documents are all mixed up too. I don't know how you keep them all straight.
