We want to be sure that participants tell us how old they are, and that they give a valid response.
Let’s click the Response Guides tab of the Question Editor to set up some rules to describe what constitutes an acceptable response to our question.
- Make this item required by clicking “Always use the following setting for this item:” and checking the ‘Required’ option.
- Assuming that anyone taking our survey is at least 1 years old, and at most 100 years old, in the Numeric/Date/Time Bounds, we’ll set the Lower Bound for this question to >=1 and the Upper Bound to <=100.
- Now let’s set an error message for this question: “Please enter a number between 1 and 100“. The error message appears whenever a participant provides an answer that does not meet the criteria we have just defined. The error message also appears when a participant tries to submit a page of the survey without answering a required question. This error only applies to this specific question.
