(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.
