require $KoolControlsFolder."/KoolAjax/koolajax.php";
$koolajax->scriptFolder = $KoolControlsFolder."/KoolAjax";
if ($koolajax->isCallback)
{
//If it is callback request, Slow down processing to see loading effect
sleep(1);
}
$country1_value = $_POST["country1"];
$country2_value = $_POST["country2"];
?>
