Doesn't work

Is there something wrong with the chain lightning trigger? The unit that's supposed to cast won't listen :<

Variable setup: (No, names aren't serious lol)

:Edit:
The spell works correctly if executed manually btw.

Can UnitTurn cast the spell if you tell it to do it manualy?

Does 'UnitTurn' have the spell Chain Lightnight (Far Seer)?
oh dang, anitarf beat me...

It has a spell based of the standard orc chainlightning.

ok then, does it have enough mana, is the target in range?

Yes and yes.
Spell range has a max of 2000 and the unit's range from target is about 700.
The spell's manacost is set to 0.

try using the 'Select a Unit' and selecting 'unitturn'

Select? Maybe i haven't made it clear enough :P hehe

UnitTurn, in this case, is not owned by me (player) it's the comp's unit. This trigger is supposed to be like an AI.

ok, have you tried testing the unit's chain lightning?

Yes, as i said, it works when used manually.

show us the map

ok...
this is mysterious.
This is why you don't use GUI.
Are there any events that trigger these actions?

Well, as most unoptimized triggers fail, it's cause of a tiny error. Seems like i had set something in the "targets allowed" that made it fail.

The reason why i didn't notice when doing it manually was because of the treaty between me and the target. When the trigger does it, it's on allied, when i do it it's on neutral.

Sorry for making such a fuss for nothing. ^^ Thanks for looking into it though.
