Roster within a roster

Dear support,
i have a questionnaire that has a roster(sources of media information) and this roster has a roster(newspapers) within it.
My problem is, how can i enable the second roster(newspapers) only when 7th option (newspapers) of the roster(sources of media information) is selected.

i tried this F3 == 1 && (@rowcode == 7) but the result it only the 7th option of the second roster is enbled…
is there a way i can enable the second roster only when the 7th option under the first roster answered as yes(1)??

And it is correct, since @rowcode refers to the item codes of the roster where it is written.

Perhaps put your second roster in a subsection ‘newspapers’ and enable it if a particular source was selected, such as sources.Contains(7).
