you can also replace that one red line with these lines, so it will only send the message out when an order has been placed (as in readme):
if ($order_info['status'] == 'P' || $order_info['status'] == 'C' || $order_info['status'] == 'O' || $order_info['status'] == 'B' || substr_count('OP', $order_info['status'])>0 ) { [COLOR="Red"]global $db_tables; include_once 'fn_sms.php';[/COLOR] }
