Hiding buttons on master slide until triggered

I am not sure what I am doing wrong. I have created a lightbox menu which you get to from the quiz results slide by clicking Review Lesson button. That menu indicates which section questions were missed. I have set a variable to true (ReviewLesson) when the Review Lesson button is clicked.

On the master slide I have 2 buttons: Review Lesson and Retry Practice. These are hidden until the ReviewLesson variable changes to true. Then they are normal when the timeline starts. I cannot get this to work. What am I doing wrong? File is attached.

I am not getting the buttons on the master slides to appear when you click an item from the review menu. In the master slide view there are 2 buttons that should appear on the slides after review lesson has been clicked from the results slide and the ReviewLesson variable has changed. Thos are what don't work for me.
