Im just trying to make a person walk... D: Help!

I've tried a bunch of different models and when I try to make them walk I move there right leg, then there upper body, then there left leg. However, when I do this there waist never moves. How can I fix this?

you have to make the entire character move, and not just its subparts. Instead of saying left leg move forward, try making the character move forward and the leg turn backwards together.

Instead of move, use rotate and roll for subparts
