An error that I can't make sense of...

[Rimer dal]

I am working on porting and updating a mod for my forum, but in the process I ran into an error that I don't recall ever seeing before.

Fatal error: Call to a member function on a non-object in /includes/functions_newpost.php on line 35

This is the code I have, the line it marks as erroring I surrounded with -| |- so it would be a little more visible. If anyone has an idea as to why I am getting this error, please help me. It might be that I am making a stupid error and I am just not seeing it...

function fetch_private_thread(&$post)
{

	global $vBulletin;
	
        if (($post['privatethread'] >= 1 || $post['privatethread'] <= 4) && $post['privateusers'])
        {
        	// get the box data properly formatted
                $privateusers = preg_split('/(?<!&#[0-9]{3}|&#[0-9]{4}|&#[0-9]{5});/', $post['privateusers'], -1, PREG_SPLIT_NO_EMPTY);                        
                foreach($privateusers as $privateusername)
                {
                       -|$privateuserarray[] = $vBulletin->db->escape_string(htmlspecialchars_uni($privateusername));  |-                              
                }

Thank you

Problem fixed, global had a capital letter 'B' which php being case sensitive got angry at me for. Problem fixed and well on the way to finishing my project.
