Need Help With Passing Var To Function

[paul41598]

I can't get this to work for the love of god, need assistance. Basically Im grabbing some data where theres a condition, if meet it sends off a PM.

I think the trouble is passing of variables. Because the PM arrays, etc arnt getting passed into the send_pm() function. I mean, I think they are but it is echoing back the wrong results, errr, wrong format anyways.

$userpointsqry = $vbulletin->db->query_read("
	SELECT score_times, ptp_log, userid, username
	FROM " . TABLE_PREFIX . "user 
	WHERE score_times >= " . $vbulletin->options['ptp_groan_amount_level1'] . "
");

$pmto_users = array(); 
				
while($pquery = $vbulletin->db->fetch_array($userpointsqry)) 
{

$pmto_users[] = $pquery['username'];  // initiliaze array for PM sending


// if rows are less than 1, PM to that person, if multiple, select ALL receipients

if ($vbulletin->db->num_rows($userpointsqry) <= 1)
{
$pmtousernames = $pquery['username'];
}
else {
$pmtousernames = implode(';', $pmto_users);
}


// Lets update the users points now
 $vbulletin->db->query_write("
 UPDATE " . TABLE_PREFIX . "user 
 SET	vbbux =  '" . $amt1 . "'
 WHERE score_times >= " . $vbulletin->options['score_amount_level1'] . "
");
 start_pm(); // SEND THE PM!!

} // end while loop



// Start Private Message Code
function start_pm()
{

echo "$pmtousernames";  //this is just for testing purposes to see what it displays

// THE ABOVE DISPLAYS    CMUrickCMUrick;Pepsico
// SUPPOSED TO DISPLAY   CMUrick;Pepsico

}

I tried putting like "global $vbulletin, $pquery, $pmto_users, $userpointsqry, $pmtousernames;" right after:
function start_pm()
{

but that didnt help either.
