To do this we'll need to access the main root of this command, the goto command--which is right above the on command in our expanded menu on the left. To insert this command, you'll highlight the line that contains your on (release) command, and then double-click on goto.
Now the options to customize the command will change to display the options for goto--letting you define if you'll use a gotoAndPlay, or gotoAndStop before setting the Scene that you'll go to on this action, the type of increment/definer, and then the number/label of that increment/definition. Go to and Play is the default, and since that's what we want to do, we'll leave it at that.
In your scripting window, there should be a command that says gotoAndPlay (1) ;. With the current settings, because Flash by default uses the current scene when inserting a new command, this would rewind the movie to Frame 1 and start it over again.
