Revisiting a Slide Functionality

It is possible to reset a slide and keep the Next button enabled. Since resetting the slide means the buttons won't be in the Visited state when the user returns, use a T/F variable to track that the interaction has been done. The value of a variable won't change when a slide is reset (unless there's a trigger that changes it.) 

• Create a T/F variable with the default value of False. 
• Add a trigger that changes the value to True when the interaction is done. In other words, use the same "when" as the trigger that changes Next to Normal. 
• On the trigger that changes Next to Disabled when the timeline starts on the slide, add a condition so the action only happens if the variable = False. That would look something like this:

Note: You could add an Else statement to that trigger to change Next to Normal. That shouldn't be needed, but it couldn't hurt. 

BTW, a “when timeline starts” triggers runs every time the user reaches the slide. That's true whether the Slide Properties are set to "Reset to initial state" or to “Resume saved state.”
