Suppose you include a non-mandatory single response question in your survey. Nevertheless, you still want a participant to receive a message, if he/she does not answer the respective question, even if he/she should be able to continue the survey unhindered.
Note: The Force response setting has not been checked.
In order to present a participant with a message when he or she fails to answer an optional question, you can proceed as follows:
Include a text block in your survey in which you record the text of the message, e.g. At the previous question, you did not select an answer, nevertheless you can simply proceed with the survey. After this, you still need to create a filter of the Calculation type.
Click the Add filter button below the text block for the Filter window to appear. On this window, you can specify the condition under which a message should be displayed to a participant.
- Show this element
- if – Calculation – q1 – = 0
After you have completed the setup, you still need to click the green Save changes button. Now the message defined in the text block will be displayed to a participant, if he/she did not select anything at question q1 (value 0).
Note: For an optimal performance of this function, it is recommended to insert a page break between the question (here: q1) and the text block.
