Hi!
The context: I have a question, of the select one type, that shows a box to put numbers on it if I have answered 'yes'. If I have answered the question as 'no', the box doesn't show. So the line of the column of numbers is empty if I have answered 'no' on the previous question.
My problem is that I need the column of numbers to be filled with 0 if the previous question was answered 'no'.
