Doubt about 'monster' script command

[Echoes]

Hello there, Echoes here New to the community..
(I searched for similar topics but I didn't found anything, sorry if there were any similar topic..)
 
This is my doubt:

*monster     "<map name>",<x>,<y>,"<name to show>",<mob id>,<amount>{,[b]"<event label>"[/b],<size>,<ai>};
*areamonster "<map name>",<x1>,<y1>,<x2>,<y2>,"<name to show>",<mob id>,<amount>{,[b]"<event label>"[/b],<size>,<ai>};

 

The "<event label>", I don't understand how to use that.
On the examples where it says how to use it, this appears.

<Normal NPC object definition. Let's assume you called him NPCNAME.>
monster "prontera",0,0,"Quest Poring",1002,10,"NPCNAME::OnPoringKilled";

 

The NPCNAME, which exactly need to be?

I have this as my actual script:

-	script	EventoPayonDungeon#1	-1,{
OnNPCKillEvent:
	if (killedrid == 1015 && strcharinfo(3) == "pay_dun00"){
		set evnt,evnt+1;
		if (evnt == 2){
			announce "Zombie Master: ¡¿Quién osa matar a mis subditos?!",pay_dun00,00xFF0000;
		}
		if (evnt == 4){
			announce "Zombie Master: ¡Se arrepentirán de matar a mis esclavos!",pay_dun00,00xFF0000;
			areamonster "pay_dun00",147,173,156,164,"Zombie Master",1298,1,"EventoPayonDungeon#1::OnZombieMKilled";
			set evnt,0;
		}
	end;
	}
OnZombieMKilled:
	set $ZombieMKilled,$ZombieMKilled+1;
	if ($ZombieMKilled == 1) goto Success;
	end;
Success:
	announce "Zombie Master: ¡Esta no será la última vez que ataque! ¡Volveré!",pay_dun00,00xFF0000;
	set $ZombieMKilled,0;
	end;
}

 

And I got this mapserv-sql error:

[Error] npc_event: event not found [EventoPayonDungeon#1::OnZombieMKilled]

 

What I'm doing wrong?

Help please C: Thanks.

Did you add your script to conf? If yes? Double check it maybe you mispelled it. If its correct? Check if you use<TABS>between headers? If yes? Try reducing script name length.

-	script	EventoPayDun	-1,{
------------------------------------------------
areamonster "pay_dun00",147,173,156,164,"Zombie Master",1298,1,"EventoPayDun::OnZombieMKilled";

Ok, I'll try.

Thanks for the advice.
