To customize it, you may also use expressions. Please note that the custom value has to be calculated before the expression is displayed. For example, no custom value is displayed if the expression and the question and/or question answer codes used within the respective expression are displayed on the same page. If this happens, then the question attribute will inherit the value established in the "slider minimum value" field.
