Hi, I need help with Appraisals. As part of the appraisal, I have several questions where a numerical scale is used - I have a question type Rating (numeric scale) and also Rating (custom scale) and as a last one I want to use a question type "Aggregate rating questions", but when editing this question I still get the message "There are no selectable options for aggregation, options must be numerical or custom ratings questions and on an earlier page than the aggregate question. "
Apparently I don't understand the correct use of this question, does anyone have experience with it and can you advise me?
Many thank
Martin
