how to restart animation

Hello, i need some help here with storyline.

i have a game on slide 3 which needs to be 'resume saved state' so that the animations can continue each time the learner completes a question.

however if the learner needs to retake the assessment, he needs to return to slide 3 and go through the animation from the start. is there any way i can make use of the variables to effect this?

thank you.
