Quiz question numbering- automatically upping every time a learner selects replay

I have a course with a variable quiz question numbering built into the final assessment.  It adds 1 each time the learner reaches a page - set to trigger when the timeline begins.  I have it clear at the beginning, on review and retry - but if the learner hits the replay button on the seek bar - it is causing the timeline to begin again and add a number to my quiz questions...and before you say - well why do you have a timeline on a quiz question...it is because on too many courses (in any number of computers, browsers and LMSs including articulate review) we occasionally get a partial load of a slide and the remainder of the slide shows only a blue or white screen (usually blue) and they only foolproof method to clear the partial load is to grab the seek bar and bam it fixes it every time. So back to my question - is there any set of variables I can use to prevent my numbering from increasing every time a learner decides to get handsy with the course and click the replay button.  I was playing around with the insert slide numbering - but I am only seeing slide that are in the menu and my quiz questions don't show up in the menu so they keep registering 0 (might be user error)  but I am thinking if that variable changes on a timeline starts trigger it might have the same issue.  Any ideas and help would be much appreciated. Thanks
