Change the state of Next button on the player?
I'm working on an e-learning project where the learner is allowed to proceed to the next slide only when she / he viewed all of the content on that slide. I managed to set up conditions with variables ( Next is only working when the learner clicked all of the buttons...etc) My problem is that there is no Inactive / Hidden state for the Next button so it can be very misleading for the learner why the button is not working.
The other solution I have come up with to disable the Next button and put it inside the slides...But I don't think it is a 100% solution.
You can view here my sample about the problem
Is there any other prerequisities configuration possibility to automating the process of disabling / enabling next button on the engine?
Or any ideas, suggestions?
Many thanks in advance,
