Please note: you will still need to configure your PayPal account for Auto-Return/PDT <em>(as instructed above)</em>.

In other words, if you use the <code>success=""</code> Attribute in your Shortcode, the initial redirection back to s2Member\'s default Auto-Return/PDT handler MUST still occur. However, instead of s2Member displaying an Auto-Return Template to the Customer, s2Member will silently redirect the Customer to the URL that you specified in the <code>success="http://..."</code> Attribute of your Shortcode, allowing you to take complete control over what happens next.</p>' .
