[Closed] Trouble animating

I’m trying to animate a character, but I’m having problems. For some reason, the head is moving to a different position than I want it on it’s own, and when I try to set a keyframe for the head in the correct position, it won’t set the key. I’ve even tried setting keyframes by auto-keying and rotating the head, and by rotating the head and then hitting set key. Any ideas why I can’t seem to animate the head and what I can do about it?
