Hi,
I would like to know how to put the condition between two questions
A °) Question
multiple choice
. choice1
. choice2
. choice3
. choice4

B °) question

Condition: B °) active question if the choice is greater than 1

Not sure is I correctly understand question.

Condition on second question should be something like this:
