	// recover persistent data - see below
	$basket = $sagepay->basket;
}

elseif ($_POST) {
	
	$sagepay->VendorTxCode = '000001';
	$sagepay->Amount       = 10;

	}
	
	$sagepay->register();

if ($sagepay->status() == 'OK') {
	// The order has been completed.
	echo "Payment complete. See details:\n";
	print_r($sagepay->result);
}

elseif ($sagepay->status() == '3DAUTH') {
	// Any data that needs to persist through 3DAUTH can be added to the object
	$sagepay->basket = $basket;
	
	// POST to ACSURL - usually by outputting a auto-submitting form
	?>
	<form action="<?=$sagepay->result['ACSURL']?>" method="post">
