Multiple result slides in the same course

Hi. I would like to know if anyone has any issues with results slides getting confused? I did a set as per this tutorial:https://player.vimeo.com/video/149073336 But I needed there to be three questions and thus, three results slide. The problem I'm having is that only the last question appears to be giving the correct results. I think it might have something to do with the Score.points variable that is used, but I cannot figure out a way around it. Any suggestions?
