st: kendall's tau or gamma

I'm trying to construct a crosstab on weighted, ordinal data. Stata will d= o the crosstab. When I try to get the gamma or kendall's tau (or any measu= res of association), it says "option gamma not allowed" (or substitute "gam= ma" for any measure I tried). Why is this? I tried the survey function, b= ut gamma and tau aren't options in the measures. Can anyone provide some l= ight here? I just need to be able to say whether or not the variables are = associated, and the strength and direction of the relationship...??
