Hello Jason.  If you provide a small illustrative data set (via DATA LIST)
along with your GENLINMIXED and MEANS commands, others might find it easier
to help you figure out what's going on.  (Folks who do not wish to take the
time to generate such an example themselves may be willing to help if you
provide it!)
