Thats my bones problem:
"When a bone is selected, it is drawn in the highlighted color, red. When you add a new bone, it becomes the "child" of the currently selected bone. The parent-child relationship for bones means that the child can move around without affecting the parent, but if the parent moves, the child will move with it. This is why it was important to draw the previous three bones in order: the thigh bone's connected to the spine bone, the shin bone's connected to the thigh bone, and the foot bone's connected to the shin bone (at least in Frank's body).
When a bone is selected, it's displayed in red. Its parent also gets displayed differently: in blue. The parent is highlighted like this for your information - sometimes you may connect bones in the wrong order and looking for the blue parent bone can help determine where things went wrong."
I forgot select the main bone(spine bone) after made the other leg bone! lol
Thanks anyway for your help people
