How many weight variables and levels do you have? I think you should
have one weight variable for each level, and only specify the stub of
the weight variables in the pweight() option. For example, if you have
your level-1 weights in variable wt1 and your level-2 weights in
variable wt2, then you would specify the pweight() option as
pweight(wt).
