FP MouseLook and Animating

I want to have my player be able to move his head and arms up and down with the mouse and the body rotate left and right with the mouse with animations (such as walk, idle, strafe, back, etc..). The problem is that when I try and do any of these things they just won't rotate. My theory is that the animation is preventing the mouse look script from rotating the objects it needs to rotate, but I need to animate the arms and stuff. (especially the arms when aiming)

(Model was made with Fuse and the animations were done in Mixamo)
