Monkey Rig Problem

Can someone take a look at my rig? I was following the instructions from the book introducing character animation with blender and can’t figure out what I’ve done wrong. If someone can download the rig and try moving the monkey’s arms. They just go crazy. If anyone can give me some other tips I would appreciate it.

Thanks!
