account admin auto button configure configured confused field general help internet marketing overrides paypal paypal-profile pref remove return seller site stage thank-you-page url website

Can someone help? I am very confused at this stage. I am new to internet marketing and I have put up one website with a PayPal button on it. I have configured my PayPal profile with the return URL for the auto return. But now I want to put up another website with a PayPal button. How do I configure my PayPal account for an auto return to this new website without having to remove the return URL to my first site?

If you are using E-junkie, E-junkie overrides the auto return URL, so you can have anything set in the "auto return url" field in your PayPal account and then put your thank-you page's URL in E-junkie Seller Admin > General Pref. > Thank you page URL
