Hi, I am using version PRO 4.0K-4b - we have authorize.net gateway set up and working - when I try to add the Paypal gateway as an option at check out I get an error on both the auth.net check out and the paypal checkout saying the member / user id isnt valid ( at authorize.net - both send to it instead of the one going to paypal ) I have both order lib's added to the custom folder - I checked my combo order form and all looks ok there - I am stumped! I can get both to work alone but not together.
Any suggestions about where to check for the error or a step I am leaving out?
Thanks!
