Insert a Score Meter that follows the learner throughout the course

Hi community! I am working on a gamified storytelling experience within Storyline. My goal is to have three separate map locations (drag your character to different locations on the map and answer scenario based questions), all part of a larger quest story experience. But, when they get a scenario question right/wrong, I want to include a score meter. Score meter would show the company gaining market share when question is correct, lose market share when questions are incorrect. The meter would go up and down accordingly. Has anyone ever done anything like that? If so, any help would be appreciated! I think I have an idea how to build it, using states and variables, but would love to see some insight from the community or maybe some examples!
