Who's online on non-vb pages request

[drives fast]

I have found all of the threads touching on this subject but maybe I am having a brain fart or something I cannot understand them.

Well...maybe it is because my non-vb pages I want this to work on are located inside my forum directory and I cannot upload another online.php file since there is already one in there.

say I have a page that looks like this:

PHP Code:

<?php
error_reporting(7);

$templatesused='guides';

require('./global.php');

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

$bbusername = $bbuserinfo[username];

eval("dooutput(\"".gettemplate('guides')."\");");

?>

and it uses a template as shown above

what can I do to make $onlineusers and $username work on that page?

thanks in advance
