using VBulletin Account for hidden html-Page

[Tobias Honscha]

Thank you very much - I think this is the code I need.
Although I inserted your PHP-code users can access the file without loggin in . What am I doing wrong ?
This is the script I am currently using :

<?php
error_reporting(7);
require("./global.php");

if ($bbuserinfo[userid] == 0)
{ show_nopermission();}
?>

.. and here comes the html - code which has to be hidden for unregistered users.
