What do you want to ask? How many answers do you want to have? Where do you want to get the values? Your question prompt will reflect what these answers will complete in your template. When only one answer will do, the Selection Variable type should be Single. When it is possible to have more than one answer, you will use the List of type. When the values come from one list of values, User Data is pointed to an Object Variable. When the values need to come from a combination of lists, User Data is pointed to an Object Formula.
