Hi there guys i am stuck in one of the animation tutorials The Walk Cycle by Kurt

I cant get the dude root to go down without moving the whole body, its annoying. on the tutorial doesnt say anything about getting the model stuck on the line so when trying to move he wont pass the grid line or the floor.

it basically when i try to bend his body by the root it wont do it just move it down, and also when trying to make the legs move forward it moves the whole body. please mate if u could help me out, that will save my life cause i got project to end it on this friday thanks
