Below is a sample PHP script that will catch all Post and Get parameters upon return and print the names of the parameters with their value back to the screen. This may help you develop your return process. Please note that we do not support third party scripts, so we also can not troubleshoot the script itself. It is being provided for your convenience only. We can help you if you are having problems receiving any passback parameters though.

<?php //display all post and get parameters

	echo "<h1>Get Parameter/s:</h1>";
	echo "<pre>";
	if($_GET)
		print_r($_GET);
	else
		echo "There are no get parameters.";
	echo "</pre>";
	echo "<hr/>";
	echo "<h1>Post Parameter/s:</h1>";
	echo "<pre>";
	if($_POST)
		print_r($_POST);
	else
		echo "There are no post parameters.";
	echo "</pre>";

?>
