I made the change . still it is not working ..

part of the code in the function called by window.open is as follows:

?>

<textarea rows="30" cols="95"><?
$val = $_GET['param1'];
$fullpath = urldecode($val);

$data = file($fullpath);
foreach($data as $value) {
echo "$value";
} ?>
</textarea>
<a id="bottom"></a>

.. Am I going wrong in placing the anchor place ?
