please how can i do to display one question with his answers set in one screen (one screen = one question)
When you use Designer to design your questionnaire – there we have text mode. You can design something and then look how it will look like.
Our system allows the user to see more options and capabilities than one question per one page. But you can try to make several sections, and put each question into one section.
When you design the questionnaire – look at it on web mode tester, it’s very useful.
