Problems about the posture

Hi,there

I have modified the PedalDemo, Referring to the ergonomic data of some vehicles , I added a pedal located in the desired position and changed the man’s posture.When I load the model, no error occurred. However when setting initial conditions, the pedal was located at the primary position, not the position I want. The manikin was in a strange position as well. I wonder what caused this problem? I have upload my model, thank you !
