Help!!! He Won't Listen!

i am making a cinematic in which a unit is ordered to move to the center of a region. He goes about 4/5 of the way but then turns around and goes back to where he came from. Can any1 help me out on this?

em... make sure he can actually WALKS there. (check the trees or bridges to make sure nothing blocked the way).
And btw, wat trigger u using?

nevermind, i fixed it, i am not sure how because i just messed around for a while wit it until i got it.
