Help macro use item in target

[Thiaguin-]

I would like a macro that uses the item in the selected monster.
The item id is 14051
The name of the monster that should be used is Hive Pore, 99 is the id of it as any player.

500 {Use Item} monsterCount:=1 shootID:=14051 Creatures.ByName(Hive Pore)>=!monsterCount! target:=Creature.Attacking() Creature.ShootOn(!target!, !shootID!)

.. try it.
