Trigger Help plz

Im trying to make a trigger that supposed to err for instance a unit casts a spell a spell equals Command follow, then all allie´s within range of 400 of the caster is supposed to right click the Hero but when i made that spell the ally wasn´t the onlay one who started following my hero but the enemy too any help would me appreciated. I´ll even add good rep.

can you show us how is your trigger written? is the condition for only ally correct?

ok a (events) unit begins casting an ability
Condition ability equals command follow then i added and multiplay conditions (i don´t know excactly im supposed to have i tryed player comparasion but i came up empty)

Then (Action) unit group - order units within range of 400 Hero to right click hero

Wait 20 second

then i order them to stop.

The condition you want is this:

((one player) is an ally of (The other player)) Equal to True

That strangly happens to be a boolean comparison, it seems wierd though.

You probably want to do

((Owner of casting unit) is ally of (owner of unit being attacked by whatever)) equal to true.

Thanks a lot man i gave you a rep im going too see if this works, if it doesn´t well i just gave you a rep for trying to help :D .

change the action before the wait to this unit group(pick all unit within range of 400 of hero and do multiple action) - if picked unit belongs to caster or allies of caster than right click hero
Its not type according to editor, but i guess this roughly tells you wat i'm thinking.

Thx but its working already.
