Character floats, fixed points not working

I can never seem to get the rigging right with fixed points.  My characters always float, the head tilt tilts the whole character instead of just the head.  Puppet file attached.  Going from multiple examples it seems to be you select the Body layer and add fixed points to the bottom of the feet, which is what I have done to no effect.  Is this the correct way, and why is it not working?  Seems like there should be a way to "auto rig" some of the basic character points for a "human" or puppet with two legs two arms, eyes mouth etc.  Most of the layer naming, eyes, mouth, eyebrows seems to map very well. It would be nice if they could expand on this and make it less tedious for simple rigging (like pin my feet to the ground by default).

Thanks in advance,

Robb
