Use PayPal Sandbox to test "Buy it Now" and ad payment
 

Has anyone succesfully used the PayPal Sanbox at https://developer.paypal.com to test the payments?

I've used the sandbox on other scripts and it's usually as easy as changing

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
to
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
making sure you are logged into devloper.paypal.com in another window.

Then doing the transaction using an email you setup in the sandbox.

I've made the change above to payment.tmpl and buy.tmpl so the buy-it-now sends the transaction to the right place, and the "user" who placed the test ad has a sandbox email in their user information, but the sandbox gives an error
Hopefully, if people are using the PayPal features this has been figured out.

Did you change your admin email in the program to the sandbox one?
