Perhaps I don't quite understand sessions yet... but why does this code always output: "0Page" ??? Thanks in advance.

PHP Code:
<?php
session_start
();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($_SESSION['count'])) {
    
$_SESSION['count'] = 0;
} else {
    
$_SESSION['count']++;
}
echo 
$_SESSION['count'];
echo 
"<a href=\"stest.php\">Page</a>";
?>
Also: I got this from the PHP.net site, so.... why does it not work?
