Récupération des Variables flashvars.

Bonjour j'utilise un script connu dans son milieu afin de prendre des photos via une web came.
Le soucis c'est pour récupérer la variable cle dans mon script flash afin de l'utiliser dans ma redirection lors de la prise de photo.

voici la page index et le script flash.

Merci
Index.php

<script src="swfobject.js" language="javascript"></script>
<script type="text/javascript">
var flashvars = {};
flashvars.cle = "<?php echo $_GET['cle'] ?>";

var parameters = {};
parameters.scale = "noscale";
parameters.wmode = "window";
parameters.allowFullScreen = "true";
parameters.allowScriptAccess = "always";

var attributes = {};

swfobject.embedSWF("take_picture.swf", "main", "700", "400", "9",
"expressInstall.swf", flashvars, parameters, attributes);
</script>
