Getting $_SESSION['var'] into javascript

I am trying to get SESSION variables set by a PHP script into a javascript.

I found the following:

[javascript]

var acct_name='<?=$_SESSION['acct_name']?>';

[/javascript]

When I place that into my javascript, it stops working.

Any ideas/solutions welcomed.

I'm not too sure, but try putting a semi-colon at the end of the line like this:
var acct_name='<?php $_SESSION['acct_name']; ?>';
