Lattice Cage Gone Wrong!

So I was following the Blender 2.5 Character animation Cookbook when I was working on the mouth. I was able to success fully create lattices on certain parts of my character’s face, but after parented to the head, well every thing went down hill. After racking my brain, I failed to see where I went wrong. The Link above provides access to the file and it was created in 2.49B.

I was able to fix the mouth, but now the forehead is not moving. Should I weight paint it to the rest of head?
