Currency Selection - Delete Item headache

[davey_b_]

The code works fine for selecting between the currencies but here's the problem...

If I leave

echo "<script type='text/javascript'> window.location='".$_SERVER['HTTP_REFERER']."';</script>"; 

enabled then the page just continously reloads, if I comment it out then all works but you can't delete any products from the cart - or anywhere else for that matter!!!

 

Here's the code...

<?php /*currency section starts*/

	$currency_selected = "";

	session_register('SESS_currency_type');

	if(isset($_POST)) 
	{
		foreach($_POST as $k => $v) $_SESSION['SESS_currency_type'] = $k;		
		echo "<script type='text/javascript'> window.location='".$_SERVER['HTTP_REFERER']."';</script>"; // <-- problem line!!
	}
	else
	{
		if (!isset($_SESSION['SESS_currency_type']) OR $_SESSION['SESS_currency_type'] == "")
		{
			$_SESSION['SESS_currency_type']	= "1";
			$currency_type			= "1";
		}
	}
/*currency section ends*/ ?>

 

Does anyone know whats wrong??
