I suspect that you use -tabulate- with the -summarize- option, but there is no 
solution within that framework for your problem.

However, -tabstat- allows the calculation of standard-errors of means for 
groups defined by one dimension:

. sysuse auto
. tabulate for, sum(trunk)
. tabstat trunk, by(for) s(mean sd semean)

If you want more dimensions the situation will be different. I usually  apply 
something in the line of

. collapse (mean) mtrunk=trunk (sd) sdtrunk=trunk (count) ntrunk=trunk, by(for 
rep78)
. gen setrunk = sdtrunk/sqrt(ntrunk)
. list for rep mtrunk setrunk


many regards
uli
