Hello, Miguel,
of course there can be a multiple question.
But you said:
Q01 YOU HAVE A LIST OF ANSWERS YOU MUST SELECT ONLY 1
If Q01 is a multiple question, just adapt the equation.
Instead of:
"Subquestion 1 of Q2 = "Y", if Q1 == 1", just say:
"Subquestion 1 of Q2 = "Y", if Subquestion 1 of Q1 == "Y""
{Q2_SQ001=if(Q1_SQ001=="Y","Y","")}
But:
I understand your scenario similar to:
Awareness of brands
1. Top of mind.
2. Total known
3. Question only about known brands (in Q1 or Q2)
This I would do a bit differently. (without equation)
Q1: multiple with setting "max 1 answer" (or more, up to you)
Q2: multiple with matrix exclusion filter Q1
Q3: multiple with subquestion relevance (e.g. Q1_SQ001=="Y" OR Q2_SQ001=="Y")

AND: PLEASE DO NOT CROSSPOST.
You asked the same question at the same time in the spanish section.
So we might waste our time as volunteers here not knowing that you already got a satisfying answer in the other section and viceversa.
