Waypoint Spawning

[chrismed0]

I'm not sure exactly how to do this. I did some looking around and tried a few things but none so far seemed to work. Still trying to get the hang of writting these perl quests.

I am trying to get a NPC to spawn in another zone on a grid when an NPC in another zone hits a certain waypoint in another zone.

This is what I got so far from reading but not sure what the missing component is.

sub EVENT_WAYPOINT_ARRIVE {
    if ($wp==32) {
         (not sure what goes here, thought maybe quest::spawn() but doesn't work)
    }
}

Thanks

Ok found a couple of posts. Looks like it has something to with globals but don't understand how globals work or how to set one up.

Just for additional information. Both zones are static. Both NPC are up and on on grids I completed. The one npc which is suppose to trigger the one is suppose to stay up and moves on a circular grid. The other one is not suppose to be up until it's triggered.
