Hi, I want to build a constraint for the following question:**
Where do you buy coffee from?
(Respondents can choose multiple responses)
Why don't you buy it from Starbucks?
I want to add a constraint here for only those who do not choose Starbucks. Even if they chose starbucks and McD i don't want this question to open. I want it to only options for answer that do not require Starbucks as an option.
