Where do I put this HOOK location so it works

[mcyates]

I'm using this Side Bar modification and that is where I want the data to be shown. I used to have Ultimate Side Columns and it worked on there but i've forgotten what hook location to use.

This is my code I'm using which shows only the current staff members who are actively on my forum. But I don't know where the hook should be called from.

// @@@@@@@ Lets See who is on @@@@@@@


$datecut = TIMENOW - $vbulletin->options['cookietimeout'];

$ForumUsers = $db->query_read("
SELECT user.username, session.userid, user.usergroupid
FROM " . TABLE_PREFIX . "session AS session
LEFT JOIN " . TABLE_PREFIX . "user AS user ON(user.userid = session.userid)
WHERE user.usergroupid IN ($group) and session.lastactivity > $datecut
ORDER BY user.username ASC
");

$StaffOnline = "<!-- Staff Online -->
<div>";

if ( $db->num_rows( $ForumUsers ) )
{ $AddedStaff = array();
while ( $LoopUser = $db->fetch_array( $ForumUsers ) ) // Loop through current users
{
if ( !in_array( $LoopUser['userid'], $AddedStaff ) )
{
// Get Username with HTML markup
$LoopUser['musername'] = fetch_musername( $LoopUser );
$StaffOnline .= "<div><a href='member.php?u=".$LoopUser['userid']."'>".$LoopUser['musername']."</a></div>";
$AddedStaff[] = $LoopUser['userid'];
} // End if in_array()
} // End While
} // End if we have rows

// Check to see if there was staff and if not show message if config to do so.
if ( count( $AddedStaff ) == 0 OR !isset( $AddedStaff ) )
{
if ( $ShowNoStaffNotice ) { $StaffOnline .= "<div>No Staff Currently Browsing the Forums.</div>"; }
}

$StaffOnline .= "</div>
<!-- End Staff Online -->";

Thank In advance for any help.

I get this error when:

Product is: Right Side Column
Hook Location is: global_start

Obviously that is wrong lol
