Move Object Based on Answer in Quiz (advance or go back)

I'm building a 10 Question Quiz where a character or object advances across the screen when the learner selects the correct answer; or goes backwards a step when the learner chooses an incorrect answer. 

I know this has been done but am having trouble getting it to work. I built something similar in Captivate almost 10 years ago, and I know I've seen examples in Storyline using sliders along with Add/Subtract Value. Will someone point me to a file that has this?
