Question bank - numbering questions

Has anyone figured this out.  I have spent hours on what seems like a simple thing. 

All I am trying to do is:

1. Show question X of N on each quiz question

    (not a problem with variables and incrementing them when the slide timeline starts

2. Be able to Review quiz and move forward and backward with Prev and Next  Showing Slide X of N
   (Seems impossible and have not seen a solution offered that works)

What I have tried...

1. Incrementing slide number

     Created Variables QuestionNumber and QuestionCount.  QuestionCount = total number of questions
     Added text box to Quiz Master Slide  Question %SlideNumber% of %SlideCount%

     Add Slide Trigger to Quiz Master Slide. Add 1 to QuestionNumer when timeline start

2. Reset QuestionNumber when user either Retries or Reviews quiz
    Add Trigger to Retry and Review buttons on Results Slide
    Set QuestionNumber =0 when user clicks button
    (Only works if it is placed before the Review Quiz trigger

3. Allow user to move forward and backward in Review Quiz Mode

    Added two Player Triggers for the PREV button on the Quiz Master Slide

    subtract 1 from QuestionNumber when user click PREV  if QuestionNumber > 1

    Jump to Previous Slide if user Click PREV button

    (This will not work because Storyline only executes the first trigger. Changing the order of the triggers results in

      only the first trigger being executed)

    Moving the Triggers from the Quiz Master Slide to the Question Slide made no difference.  Only the first Trigger is

executed regardless of the order.

In my humble opinion this is an ERROR of Storyline.  The only way to effectively use question count is to TURN OFF

Review Results.
