(1) Your question is far too vague for anyone to be able to give you a
useful response. You should provide a small reproducible example of
what you are trying to do and a clear explanation of what problems you
are having in trying to do it.
(2) Questions about mixed models are better addressed to the "special
interest group" R-sig-ME.
