Channel target options

Does anybody know how they work? I've been trying to make an ability that only target allies. Does it have to do with the base order id? I've been trying both Allied and Friend, but to no avail...

EDIT: It seems like setting 'NOT SELF' caused this. Odd.

Just make the "Not self" deselected may slove your problem, see what I had done:

You will unable to target the unit itself if you don't select "Self".

Ah! So it works after all... Big thanks.
