Betreff: st: combining frequency tables

Hi listers,

Another (perhaps) simple question: is it possible to add different 
frequency tables together to form a combined single table in Excel?

I have two group variables (say, var1: type of treatment; and var2: time 
point of observation) and 5 use variables. So an observation would be for 
treatment A at time point 1. I want to know the number of missing values 
for each use variable for each treatment group and each time point. Also 
for each use variable there are 'if' conditions, so I can't do the 
frequency count in one go. Here is what I am doing using a user written 
programme -mdesc- or -missing-:

by treatment timpoint: mdesc use1 if (condition1 condition2)

by treatment timpoint: mdesc use2 if (condition3 condition4)

and so on. 

 
Now I want to combine all these counts for all timepoints and treatment 
groups to get a single table that I can export to Excel. Is there any way I 
could do that?

Thank you,

Shehzad
