All, I do not know how to turn on IPNs within Sandbox. Can someone help? I've looked and looked but cannot find it. I would appreciate your help figuring out what my problem is! I am testing a new payment system that uses the Cart Upload feature with IPN. I have tested my listener script with the Sandbox Test IPN tool, and it works as I expected it. When I place a test order, I can go through the entire checkout process without fail. However, when I return to my website to look at the status of the order, it remains unupdated. I believe it is a setting in Sandbox. But, I do not know how to turn on IPNs within Sandbox. Can someone help? For those that want to know, here is the HTML for my cart: <form action="https://www.paypal.com/cgi-bin/webscr" method="post">
