triggers for dart game with 3 question banks

I'm trying to make a darts game where the learner clicks on a dart board and depending on where they click they are taken to 3 different question banks with easy, medium, and difficult questions. I'm stuck making the triggers work after the first question. I'd like the first dart to stay where it was thrown on the board when they return for the second question and so on for a total of 10 questions. The Storyline file is attached. Thank you in advance for everyone's help!
