'Next' Button functionality
I am trying to build some functionality into the Next button on my scene. The button is set to Disabled, and only changed to Normal when the timeline ends (ensuring people read the page and listen to the audio!)... however, if someone clicks the Back button, I would like the Next button to be immediately available so that they don't have to listen to/read the whole page again if they have hit it by accident. I can't for the life of me work out a combination of triggers to get this working, so any suggestions would be gratefully received!
