I attempted to create a new Variable Trigger for the button set but was unsuccessful!

Hi Tom,

Thanks for taking time to respond to my post! I really appreciate you for that! The course contains 6 topics that can be completed in any order (because I don't know how to tell it not too), a congratulations slide, and a final knowledge check. When I preview the entire project  it goes wonky at the end. Oh, I forgot to mention the course is tiered each topic has it's on lane. I'd send you a screenshot but Storyline is frozen. 

The other problem I am facing is when I attempt to create a new variable trigger it doesn't allow me to. What I mean is the trigger wizard will appear, I click the parameters I think I need but nothing happens after that but Storyline blinks but doesn't put the newly created variable trigger in the triggers menu?

Thanks again,

Stephanie
