I just set up a nice pay now button for my website and want to redirect the user to a specific page after checkout. I am attempting to do this via the hidden input named "return", just as paypal documentation specifies:

<INPUT TYPE="hidden" NAME="return" value="'$successful_url'">

the $return_url, in my case, is dynamically generated via php and outputs something like: https://example.com/confirm_transaction.php?product_id=1

My problem is, that, despite using the correct syntax in my HTML form, paypal always redirects the customer (which of course is me as I am testing my implementation) to the default return URL specified in my (business accounts') account settings.

Any help with this issue would be greatly appreciated.

Cheers
