Changing the state of a button to active only when all 3 layers have been visited
I hope you can please help? I'm new to Storyline and I've been scratching my head with this issue.
I've created a slide in which I have 3 pieces of information that users need to read. I want the 'next' button I've created to be disabled, so users are unable to move to the next slide until all 3 pieces of information (3 layers) have been read. At this point the 'next' button changes to a normal state for the user to proceed.
I've created 3 buttons on the machine visual (see attached file) that the users need to press. Each button triggers 'view layer' which then triggers a motion path.
How do I create a 'state' for the next button to appear when I don't know what order the users will press the buttons? There are 3 triggers on each of the 3 layers. Is this the correct way to build this slide?
I hope this makes sense? I'd be grateful for any help with this.
