I am trying to create a Game in Storyline 360, however my Trigger Wizard and the tutors Trigger Wizard have different fields and I'm unable to progress to getting the Dice to roll variable numbers. What can I do?

The tutorial you are viewing uses the old Trigger wizard.  For you, just keep in mind that most of the words in the sentences are selectable. For example, selecting the word "variable" will allow you to change it to value. Selecting "When User Clicks" will let you select a variety of other trigger actions, including when the timeline starts.
