How to direct PayPal to success.php

For some reason paypal express is not working for us. The window opens and closes momentarily, so we have to use PayPal. The problem with PayPal is that when the user is done paying, it doesn't direct them to success.php. Instead, the user has to press "reutrn to merchant" to enable the sucess.php script.


Is there any javascript I can write that bypasses this? And when payment is confirmed, sends the user directly to success.php?

Some Information I found on this, partly aged, but possibly still helpful.
