Short description
This question type lets the author create an equation (e.g. a calculation or tailored report) and save it in a database variable. Equations can use any syntax supported by Expression Manager. If you are handling numeric values make sure that you use the advanced question setting 'Numbers only' as explained below.
Core settings
Advanced settings
Description
If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:
- If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
- If you wish to store or calculate a value on the fly via the ExpressionScript - Presentation.
Note: A common question type that is used with this function is the Equation one.Available options
- On
- Off (default)
Note: unlike all other question types, if an equation is hidden, it is still computed and its value is still stored in the database.
Insert page break in printable view (page_break)
Description
This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.
Available options
- On
- Off (default)
Show in public statistics (public_statistics)
Description
This attribute allows the survey administrator to chose if a particular question results should be displayed to the survey participants after they submitted the survey.
Note: To have the statistics displayed on the last page, do not forget to enable this functionality from the presentation & navigation settings. Otherwise, no statistics link will be displayed at the end of your survey.The default setting for each question is 'Off' (=Do not show the question statistics to the respondents). You have to enable this for every single question if you want to show the survey statistics of that (those) particular question(s) to the survey participants after the survey submission.
