Me sale error al descargar

Hola a todos. Me da error una quest y no veo el fallo. ¿Me podrían decir dónde falla la quest, por favor? 

quest red_dragon_desert begin
	state start begin
      function setting()
        return {
          ["mob_kill"] = 2191,
          ["spawn_mob_id"] = 2291,
          ["min_party_members"] = 4,
          ["spawn_mob_coordinates"] = {870, 637},
          ["necesaryJobs"] = {[0] = "warrior", [1] = "ninja", [2] = "sura", [3] = "shaman"},
          ["message"] = "El Dragon Rojo ha sido invocado."
        }
      end

      when kill with game.get_event_flag("red_dragon_desert") == 0 begin
        local setting = red_dragon_desert.setting()
        local vnum = npc.get_race()
        if vnum == setting.mob_kill then
          if not party.is_party() then
            return
          end

          local pids = {party.get_member_pids()}
          local partyMembers = table.getn(pids)
          local readyJobs = {}

          if partyMembers < setting.min_party_members then
            return
          end

          for i = 1, partyMembers do
            q.begin_other_pc_block(pids[i])
            if setting.necesaryJobs[pc.job] then
              readyJobs[setting.necesaryJobs[pc.job]] = pc.job
            end
            q.end_other_pc_block()
          end

          if table.getn(readyJobs) < table.getn(setting.necesaryJobs) then
            return
          end

              mob.spawn(setting.spawn_mob_id, setting.spawn_mob_coordinates[1], setting.spawn_mob_coordinates[2],1)
              game.set_event_flag("red_dragon_desert",1)
              notice_all(setting.message)
          end
      end

      when kill with game.get_event_flag("red_dragon_desert") == 1 begin
          local setting = red_dragon_desert.setting()
          local vnum = npc.get_race()
          if vnum == setting.spawn_mob_id then
              game.set_event_flag("red_dragon_desert",0)
          end
      end
	end
