Game board not functioning properly at one specific point, can't figure it out.

Hey all. 

I have built a game board for use in final assessment quizzing. The premise is that the user rolls a die and the player piece moves around the board. As it lands on a space, the user will answer a quiz question brought up by lightboxing a separate slide. If they get the question correct, they earn the points stated on the space, but if they get it wrong, they roll again. 

I have built out the shell of the game currently and will add the questions later so there are no questions loaded. As a placeholder, I have a blank screen that I can X out of to continue. 

The game works perfectly, except at one very specific point. When the player piece lands on the 5 space (worth $200), the question slide doesn't lightbox. Worse yet, it will continue to go through the entire sequence of spaces, only stopping once it has reached the end of the board. 

This only happens on the 5 space - all the rest of the spaces works as intended. I have searched this for days and cannot find the error in coding. 

I have attached the .story file (if anyone wants to use/copy/etc. the project components, you have my blessing). 

If anyone can help me find the needle in this haystack, I would very much appreciate it.
