Npi won't go from idleanimation to walk animation when patrolling

[FONT=“Helvetica Neue”]So I am using this set of videos and its really great but the problem is I am using a customer character that I have sent through mixamo and got some animations and followed the ue4 live video about setting up the character and the animation montage. Unfortunately my npi character is in the idle pose but unfortunately stays in that idle pose. He will not go from idle to walk pose and would appreciate everybody’s help. Thank you and have a great day.
