Expression for bones.

Hi friends,

I can’t make such a thing:

I’ve got an armature, called “Armature”. Armature has got two bones “Bone.001” “Bone.002”. I want to make a python expression for pydriver “Bone.002”.

I want that: Bone.001.LocZ = Bone.002.RotX
But I don’t know how to make it. I’m a newbie in python.

Thank you beforehand.

EDIT After testing what I had posted here, it didn’t work since bone curves don’t seem to be driveable.

Sorry, I didn’t get. So, are bones not driveable? :((( It’s too bad.
