Thanks for the help Jason.
Everthing works now.
Just in case anyone reading this thread has the same problem:
My mistake was putting an addition Authenticate User behavior on my login page when all I needed to do was add the "Role" session variable to the 2 existing session variables that were already in the Login page that was created by the wizard. (not sure why there are 2 Authenticate User behaviors, but I put it in both and it works)
