Using Vbulletin Variables in External PHP

[grey_goose]

I've got an external trackermini.php that I've got inserted into the postbit_legacy. It's working, with static data.

What I'd like to do is pass variables from the poster's info to the script -- but I can't seem to snag them. How do I grab fields from the POSTER to use?

Plugin at SHOWTHREAD_START

PHP Code:

$templater->register('post', $post);
ob_start();
$var1 = $vbulletin->userinfo['userid'];  <-----  LOGGED IN USER VARIABLE WORKS
$var2 = $vbulletin->post['field109'];  <-----  NO WORKY
$var3 = $foruminfo[title_clean];   <-----  GLOBAL VARIABLE WORKS
  require_once('includes/trackermini.php');
  $trackermini = ob_get_contents();
ob_end_clean();
vB_Template::preRegister('postbit_legacy',array('trackermini' => $trackermini));
