Infestor auto-cast Fungal Growth {make autocast not target the casting infestor?}

[Klasus]

I have tried to make my infestors automatically cast Fungal Growth on enemies, for some reason they always end up casting it on themselves. This is how my filter looks:

Field Infestor - Fungal Growth
Ability: Auto Cast Filters Required: Visible; Excluded: Self, Ally, Neutral, Structure, Resource (Raw), Resource (Harvestable), Missile, Destructible, Dead, Invulnerable

What should I do to make them cast it on enemies only?

Try a validator that makes sure that there is atleast 1 enemy unit in the area before they cast.

ok, does that validator already exist or do I have to make a custom one?

EDIT:

I found out how to fix it, I used the "Target is enemy" validator.
