You are right GuidedTrack does not have a built-in way to create a ranking question.
One way to construct such questions could be something like this.
It lets you specify items that you want the user to rank. It asks which one they want to choose, then removes the one they pick and asks it again, and so on until every item is ranked. Creates a collection specifying the order that they picked the items in. Takes variables
rankQuestionText as input. Produces as output:
selectedOrder. You can also set
numberOfSelections as input if you don't want them to rank all items but only a smaller number of top items.
Here is an example of how to call this program from your survey.
