sub EVENT_ENTER (proximity) question ?

[Huppy]

Am I doing this right ? Goal here is to depop another npc when in proximity range of this quest npc. At the moment, nothing is working in the script.
I figure I must be missing something here. Thanx


sub EVENT_ENTER
{

{

my $x;
my $y;
my $z;
my $h;

$x = $npc->GetX();
$y = $npc->GetY();
$z = $npc->GetZ();
$h = $npc->GetHeading();


quest::set_proximity($x-40,$x+40,$y-40,$y+40,$z-40,$z+40);
quest::say("Your late!");
quest::depop(npc_type=205091);

}

}
