I need to create a enw php script amd do the following!

[Dismounted]

That won't work, you must switch to the forum directory using chdir() for global.php to include properly.

PHP Code:

$curdir = getcwd();
chdir('./forums');
require_once('./global.php');
chdir($curdir);

if (!$vbulletin->userinfo['userid'])
{
    print_no_permission();
}

switch ($_POST['selected'])
{
    case "John T Heard Lodge":
        $vbulletin->url = $vbulletin->options['bburl'] . '/forumdisplay.php?f=30';
        eval(print_standard_redirect('redirecting to forum', false, true));
        break;
    case "The Tyrian-Acacia Lodge":
        $vbulletin->url = $vbulletin->options['bburl'] . '/forumdisplay.php?f=31';
        eval(print_standard_redirect('redirecting to forum', false, true));
        break;
    default:
        echo "Invalid page";
        break;
}
