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.
