Hi,

I'm unsure of the right way of passing variables between webpages and paypal.

Basically, I have a php page with 2 variables: $email and $serial_number. In this page. I copy $serial_number
to $custom then call a paypal payment page. I can see the page is prepopulated with $email. And I know $custom
is not shown. Then, if payment is done, the user is redirected to another php page.

What I'd like to do is using the 2 variables $email and $custom in the second page (when payment is done.)
Is it possible? Are these variables returned or do I need to do something?

Thanks in advance for any clue.
