I'm no specialist for statistics or the GLM proc, but as far as I see, you
have no error. The warning relates to some definitions in your model and in
your test statement. You should have a look into the documentation or the
online help and see, how you can adjust the "degrees of freedom". Maybe
you'll understand better, what the terms there mean.
