Marker variable trigger
New to my role and Storyline (I've been using this for about 3 weeks now), so forgive me if somethings are not explained thoroughly. I've also searched here and Google for solutions.
So, I have a slide with 6 markers on, each marker has been assigned a variable to false, when the markers content closes that sets its variable to true. Now, I want a next/continue button to change its state to normal (hidden as intial state), once all the markers variables become true. I've tried to do this with when Timeline ends, as it would never be true for when the timeline starts, but obviously that is not working, and for the life of me I can't figure out what the 'When' would be.
I'll attach the .story file of the single slide, any help you can give me to solving this would be really appreciated. It's already crashed on me twice haha.
