I would like to set a filter condition on a question, so that it appears only if the respondent answered the previous question. Both questions are multiple choice questions.
Ex :
Q1 " Who do you know well among these guys? "
Possible answers : mister A, mister B, mister C
Q2 " With whom have you ever been to a concert? "
Possible answers : mister A, mister B, mister C ?
I know how to filter the answers for Q2, based on the answers to question Q1. But I would like Q2 to appear only if the respondent answered Q1.
