Disable the next button until user clicks certain button on slide
I have a slide that provides some information to the user. On the slide I also have two buttons, that when they are pressed, the user gets some more information from a hidden layer assigned to that button.
I want a few things to happen on this slide:
The user cannot use the Next button ( custom button ) until they have clicked on both of the slide buttons, to ensure they hav viewed the content.
If they attempt to click on the Next button, they get a small message saying they must view the content first, before they can proceed.
Hoe do I do this please?
