Hello Masters !

I am facing a strange problem.

With the sandbox, I always get the IPN on notify url, and return url. But when it is live, (not sandbox), only the Notify Url gets the txn id, and the return url (normally the Thank You page do not have anything in the POST, or REQUEST (PHP).

I tried to access the txn id like this

if(isset($_REQUEST['txn_id']))
{
echo $_REQUEST['txn_id'];
}

and it never get the txn id.

However, as i said, in SandBox environment, there is no problems.

Please guide me how to deal with this issue.

thanks
ZH
