Newbie question on communion

[Saxon]

Sorry if I am being thick, but I can not script spells he can not cast before he gets the level boost. Is there a trick to that?

Also, is there no way to see that his level has gone up? When power of the spheres is cast I see his level go up.

I know he should be able to cast more spells but he does not seem to do so. In fact, he keeps casting body ethererel over and over! He cast quickness and then cast body ethererel twice in the same turn. As that was the first spell he was scripted to do, it was the second and third castings...
