esion thanks that did it, and thanks all who tried to help too

I cant really explain it any better than I did, except his whole body moves with the leg and it shouldnt. His body should stay put and only his leg should move, sorry if I'm not clear but I new at...

I downloaded the walk cycle and I wanna know why when I move his foot foward his whole body moves with it.

My question is that every time I move the guy's foot his whole body moves forward with it and I just want to move his foot. How do I fix this?
