Scenario slides: how to lock or hide navigation buttons?

Hi, Zane,

You can disable the Next button when the timeline starts, and then enable it with triggers on the Consequences bases. 

FYI: In that sort of situation, I typically use a T/F variable in the condition that disables Next. That is, the trigger will only disable Next if the variable = False. Then adjust the variable to True when the interaction is done. That prevents the Next button from being disabled again if the user returns to the slide. 

You can see how this is done in the attached file.
