this code solved the problem!!!!!!!!!!!!!!
ok so now I can move on.. I will post 1 other questions now:
1) so now I am able to process paypal.. but what if i want to also process another payment channel using credit cards as well?? what i mean is how do i use both paypal and a normal payment channel through lets say my bank, if i ask my bank to give me the API to process through their channel?
.. when i used the wizard i was asked to give the API for the paypal.. but not the API for another payment channel why??
