php - Redirection to the original site after purchase is completed in Paypal

Question

I'm making one web app. I've integrated Paypal in it using simple form submission to the Paypal site. Everything works well. but whenever the payment gets successful it should redirect back to my original site with the response from Paypal. However, it's not working as it should be. Currently it stays on the Paypal site only.

<form action='https://www.sandbox.paypal.com/cgi-bin/webscr' method='post' name='form'>
 <input type='hidden' name='business' value='<?php echo $paypal_id; ?>'>
<input type='hidden' name='cmd' value='_xclick'>
<input type='hidden' name='item_name' id='item_name' value=''>
<input type='hidden' name='item_number' id='item_number' value=''>
<input type='hidden' name='amount' id='amount' value=''>
<input type='hidden' name='no_shipping' value='1'>
<input type='hidden' name='currency_code' value='USD'>
<input type='hidden' name='cancel_return' value='http://yoursite.com/cancel.php'>
<input type='hidden' name='return' value='http://mysite.com/user_credits/purchase_credits'>
<input type="image" src="https://paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" name="submit">

what am I missing in it? I'm using CakePHP 2.0.
