I don't find this very clear. 

It sounds as though you want the mean percents and 
should specify that. 

If your variables are already percents, don't use
the -percent- option. 

The FAQ (very recently revised) at

may also help. 

By the way, it helps to see the _exact_ code 
you are using. What you give is not legal code, 
as it includes illegal variable names and an 
illegal command name, 
so it makes one wonder how much else you are 
changing in your report.
