How to cloak and keyword track together ?

I have set up the cloaking using the jump.php page and .htaccess.
But I am trying to get the keyword tracking also to be inserted into the jump.php page

This is what my jump.php looks like.
I cant seem to get the "kw" to pull the data.


<?php

switch(strtolower($_GET['to']))
{
case 'jumptexthere';
$URL = 'http://afflinkhere.com/1234?sub=<? echo $_GET['kw'] ?>';
break;

}

header("Location: $URL");

?>

 

make it look like this

<?php

switch(strtolower($_GET['to']))
{
case 'jumptexthere';
$URL = 'http://afflinkhere.com/1234?sub='.$_GET['kw'];
break;

}

header("Location: $URL");

?>

Code (markup):

 

I must be missing something, but this does not work.

'.$_GET['kw'];
