- Define a MM answer type.
AAA value 1
BBB value 2
NONE value 3
- Define a question and assign above MM answer type; choose 1 required answers.
- Define a Text box question.
- Create dependancies:
-> Hide if MM question is: NONE
-> Require if MM question is: AAA or BBB
The survey will always show the Text question (unless I am doing something wrong).
