Hide "Exit Course" button until all scenes have been visited.

Hello!

I'm very new to Storyline (less than 2 months.)

I have a slide where a learner will need to click three different buttons that will each take them to a scene. At the end of each scene it will take them back to this slide.

I want to hide the "Exit Course" button until all three scenes have been visited.

Through research I've set up triggers to only allow it to show once all the buttons states are set to Normal which will only happen after they've been clicked and visited, but I still can't get the exit course button to show.

Thank you!
