How to setup a slide to show if all other slides have been viewed?

Hi Marcus - welcome to Heroes!

Without seeing how your tutorial is set up, it's a little hard to provide a definative solution to your issue but you're right in stating that you will need a trigger for the final slide that has to meet some conditions to only display if all 5 demos have been viewed.

Assuming that each demo is on its own slide, you could create 5 T/F variables (called "Demo1", "Demo2" etc.) and set the default value to FALSE. Then, on each slide, apply a trigger that adjusts the corresponding variable to TRUE when the timeline of the slide ends and then add a second trigger that jumps to the "Course review" slide when the timeline ends on condition that variables Demo1, Demo2 etc. are equal to TRUE.

As triggers are executed from top to bottom within the trigger panel, you will need to make sure that this second trigger is BELOW to trigger that adjusts the variable.

I hope that this makes sense
