Hi. I'm wondering if it's possible to block people from giving certain answers depending on their answers to preivous questions.

Example
Question 1: Are you allergic to nuts?

• No
• Yes

Question 2: What is your favourite food?
If question 1 = No

• Pizza
• Apples
• Chicken
• Nuts

If question 1 = Yes

• Pizza
• Apples
• Chicken

Right now, the best way I can find to do something like this is to create 2 different questions and send the users to each one depending on their answer to the first question using conditions. I would rather keep all the results for question 2 in one place, so I was wondering if there was any way of disabling certain answers depending on a participant's previous answer.

To be honest, the solution with two separated questions is the easiest.

And the only item we have to care of is "nuts".
As a list(radio) question doesn't have "subquestion relevance" you have to do this many times explained procedure.

Between the two questions (Q1 and Q2) create a (hidden) question of type "multiple" (Q2m) with the four items

1. Pizza
2. Apples
3. Chicken
4. Nuts

In the "default answers set "Pizza, Apples and Chicken" to "checked" (they are always displayed)

Then create a (hidden) question of type "equation" with
{Q2m_4=if(Q1!=1,"Y","")}

Now you set the array filter of Q2 to Q2m.

Remember:
The codes of the multiple question and your second question have to be identical.
The two questions can't be displayed on one page.

Thank you for answering. In the end I decided to go just add a warning on the next page if a participant's answers don't match up. Still, really happy to get an answer to this question so I know for the future.
