Select NEW PAGE under Questionnaire to add a new level to the question tree. You can change the order of the question levels by clicking on the arrows. Conditionals: Opacity 3 is only queried if NO was selected for opacity 1. Opacity 2 is only queried if YES was selected for opacity 1. So that a suitable product can be recommended, very general questions are asked first, which then become more specific. The questions are asked in the order from top to bottom.
