Students Getting Stuck at "Random"

I assigned THIS activity that I created and used some copied/edited code from other Desmos. Students would have all the correct answers and be able to advance slides but other students with all the correct answers were not able to advance a slide. This happened to multiple students. Anyone know why?!?!

The CL script for screen 7 includes:

coverText: when not(button1.pressCount=1)  "🙃 Oops!  You need to check your graph on the last slide 😝" otherwise ""

This means that students will not be able to view screen 7 unless they have pressed “Check my Graph” on screen 6 exactly once. If they press “Check my Graph” more than once, they will never be able to view screen 7. I would change the script to

coverText: when button1.pressCount=0  "🙃 Oops!  You need to check your graph on the last slide 😝" otherwise ""

I know at least a couple slides have the same sort of condition that you may want to adjust, but I’m not sure exactly how many. Good luck!

Thanks SO VERY MUCH!
