Combine Repelling

Hello,

I am wondering if anyone knows how to make a combine repel. But wait there is a catch, I would like the combine to walk/run to the edge then repel. What I tried is a npc_combine_s with a npc_template_maker. The npc spawns and runs over to the assault_assaultpoint and i made a output saying:

Onarriaval Combine BeginRepel

and when he gets there he doesn't repel. The assault point is on the edge but not in the air. He does not go to the assault point unless its on the ground near him. I also tried a path_corner neither did that work. Please if someone has an answer it will truly be a help. Thank You
