Character Animator puppets using props

Hello,

I'm fairly new to AE Character Animator and have been using it without too much trouble. I wanted to take my puppets up a notch and incorporate props for them to use. I am running into trouble because I have a scene in which a character is playing a guitar. The left hand responds to the draggable left pin and move on its own, but the right does not; it just moves the entire torso.

I think it has something to do with how the mesh is reading the puppet in character animator or how I'm labeling the layers in Photoshop (please see attached pictures). I have not run across a forum with this particular problem yet, so if anyone has any answers, I would appreciate it.

Thank you,

DN Ellis
