Ability order strings

I have mana shield for 2 heroes in my map. If I happen to have both of those heroes and bot of them selected, when casting mana shield, they both activate and deactivate. If I only select one of them, it works ok. What exactly would I need to change so that they don't mix?

You are saying that if you select them both then use mana shield on both it would activate both, I dont see the problem here. Select one to activate one, select the other and activate the other..

I think he means that they activate and then deactivate when he uses the ability, not sure though.

You're kind of right " I think ".

Say I've grouped both heroes at a time. I have one of them highlighted and activate mana shield. It will also activate my other heros mana shield simultaneously. Likewise for turning it off.

If I only pick one hero without grouping them, it works fine.

by grouping them, do you mean like ctrl+1 or by selecting them in a group?
not sure what you mean by highlighted

I dont believe there is any way around this, unless you completely trigger that spell and have a custom ability on each unit, and then use TriggerRegisterUnitEvent(trigger, unit, EVENT_UNIT_SPELL_EFFECT) on each unit you want, seperately activating and triggering each ability differently.

CRAP!!! Don't really feel like triggering it, but I guess I shall. Thanks.
