Nutcracker Jaw Problem

Hello All,

I've been working with Character Animator for quite a while, but haven't had to use nutcracker jaw before. I have a project that I need to utilize it for and for some reason I cannot get the mouth to move in the manor I'd like. I'm trying to mimic the style of jaw on the demo puppet bongo. The problem is I cannot seem to get the lower jaw from moving correctly even after pins and sticks. Either the entire mouth wants to move with the puppet completely warping it or the pins and sticks I put in don't take effect and the jaw moves separately. I have to be missing something. I've tried rigging it in several different manors from the bottom jaw being independent, to the whole mouth being independent. Any advice?
