I have a question about changing the number of questions based on a users input. Specifically, say a user answers 5 to a question, how would i then display 5 input boxes for the user to enter their input into.

Example:

Q How many cars do you have?

User enters 2

What is the brand of car 1?
What is the brand of car 2?



Example 2:
Q How many cars do you have?

User enters 4

What is the brand of car 1?
What is the brand of car 2?
What is the brand of car 3?
What is the brand of car 4?

Use a multiple-short text with sub-question relevance.

Yep, i've tried that but the real functionality I was wondering about was if i could change the amount of sub questions that was asked based on the user input. For example if a user enters 5 then 5 sub questions would be generated and if they say 2 then two sub questions would be generated.

Exactly as Tpartner describes. You need to create a certain number of subquestions and hide/show them via subquestion relevance, based on the number of questions they enter.

There is no way to dynamically add subquestions. You need to create them first and hide/show them according to need.
