How can I pipe Q8 rows that have either column 1 or column 2 selected into rows for Q45?
There is not a built in functionality for piping from table to table (table/grid questions are not available as source questions for piping).
As an alternative, I suggest applying logic to the individual rows in your Q45 to determine when they show (based on the rows in Q8):
Hope this helps!
