WTF have i done wrong

[forrie]

i have a form that is ment to send a user's Name to my custom page but i cant seem to get it working heres the code

<form action="../addreview.php" method='post' name="reviewform" > 

<input name="User" type="hidden" /> 
<a href="javascript:getreview()">Add Review</a> 
</form> 

<script language="JavaScript" type="text/javascript"> 
<!-- 
function getreview () 
{ 
document.reviewform.User.value = ' $bbuserinfo[username] '; 
document.reviewform.submit() ; 
} 
--> 
</script>

if that code is correct i should be able to use $user = $_REQUEST['User'];
right

cheers forrie
