Please note that in your Manage Project Variables panel, you will notice additional variables; these variables are associated with the After example and will have the prefix AFTER.
On your Exercise slide 1.1, you will see that there are four circles below the slide content; these circles navigate from one layer of content to the next. The first thing you will need to do is create triggers for Oval...
