Why cant my enemy move?

Ive tried to change the system of movment and mess around but i cant seem to see why my Enemy wont move, here is the link, http://flowlab.io/html5/bin/1298576

Why are you moving Y? it’s seems its also moving in the ground.
Also increasing the number would create a bigger movement (like 8)

For red enemy, proximity needs to be set to player and not trigger once
