@DebyinkThanks a lot for help, now it would be solved.
I have Cube Cart V5 installed and have activated PayPal Standard as payment method. On a test sale, the PayPal screen comes up and asks 1) Login to your PayPal Account, 2) Use your credit card. How do I link this to my PayPal account so that purchases are registered to my PayPal account? walgreenslistens
