Targeted spell trigger help

I can't get this targeted spell trigger to work..

Rainbow Spray Select

Rainbow Spray Actions

Unit - A unit Finishes casting an ability

Conditions
((Ability being cast) Equal to Rainbow Spray ) or ((Ability being cast) Equal to Rainbow Spray (ill))
Actions
Unit - Create 1 Caster M1 for Player 4 (Purple) at (Center of ACastZone <gen>) facing Default building facing degrees
Unit - Order (Last created unit) to Neutral Pandaren Brewmaster - Drunken Haze (Random unit from (Units in CSRegion[6]))
Unit - Add a 3.00 second Generic expiration timer to (Last created unit)


In this case, the Wisp is created, but doesn't cast its spell. Basically this spell is a forked lightning + drunken haze, and the Wisp is supposed to haze a random unit in the area if any units are still alive. The Wisp's spell doesn't have target restrictions (air, ground, neutral) and if I manually make it Drunken Haze, it will Drunken Haze any unit I pick immediately and without question. (Range 99999, mana cost 0, etc. etc.). The order string is correct as well. So I'm not sure why the wisp isn't targeting a unit. My spells that target the caster itself work, so I'm thinking its some sort of problem with the trigger. Any one know what I'm doing wrong?

okay, try this...


Go into the ally priorities properties menu under scenario, and for every enemy of player 4 pick *none for their pritority. For some reason if this is set to high summoned units cont cast spells on units of other teams or forces if this isn't set. I had the same problem myself.
