Return url in paypal

[DeepaVaith]

Hi,
  I'm working on Joomla 1.5 and VM 2.0.1f.  I'd like the user to be redirected to my website after the payment in Paypal is
complete.  Can someone tell me how it can be done.  I have set the return_url in the paypal.php file, but it does not seem
to work.

Thanks,
Deepa
