Hello Lee,
Can you please provide the code you are using. From asdocx help file, I have tried the following code and it works fine.
sysuse auto, clear
asdocx ttest rep78==0, replace title(T-test results : mean == 0)
asdocx ttest price==0, rowappend
asdocx ttest mpg==0, rowappend
asdocx ttest turn==0, rowappend
asdocx ttest weight==0, rowappend
asdocx ttest length==0, rowappend
using rowappend with by() option
asdocx ttest mpg, by(foreign) replace
asdocx ttest mpg, by(foreign) rowappend
asdocx ttest price , by(foreign) rowappend
