Before we explain the different types of interactivity in greater detail we'd like to point out that each time you define an interactive element in the questionnaire there are two or more questions involved. One question influences the interactivity, and other questions are influenced by the defined interactivity.
The influencing question we call an originating interactive question, since the interactivity finds its origin in this question.
The influenced questions we call receiving interactive questions, since these questions are on the receiving end of the interactive construction. The questions 'receive' information from the originating question to which they need to adapt themselves.
A question that receives information from an originating question can never be placed before that originating question. Note that a question can be both an originating and receiving question at the same time.
The MDD shows if a question is an interactive origination or receiving (or both) question by showing an icon containing the letter 'O' for 'originating' or letter 'R' for 'receiving' on the question text line just to the left of the question properties. It is important that you grasp this concept, since it will help you understand how to define interactive surveys in the Metatude Dialogue Designer.
Figure 15: Icons just left of the question properties show if a question is an interactive originating or receiving question.
