A PHP solution to your problem is to save the x y co-ordinates in a
session and do a refresh, then get the values fom session.
Do something like
<?php
session_start();
if(isset($_SESSION['x']) && isset($_SESSION['y'])){
//do your thing here
unset($_SESSION['x'];
unset($_SESSION['y'];
}else{
//get x and y from request variables here
if($x && $y){
$_SESSION['x'] = $x;
$_SESSION['y'] = $y;
header('location: '.$_SERVER['PHP_SELF']);
exit;
}else{
//show start page
}
}

Tom
