Under Questionnaire, select NEW PAGE 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 prompted if YES is selected for Opacity 1. So that a suitable product can be recommended, first quite general questions are asked, which then become more specific. The questions are asked in order from top to bottom.
