Switch function does not work

[pandadrivers]

I follow the tutorial, at the Custom commands page at the bottem there is an explanation about the switch function. But when I do this and run the game I am getting an error on the keys: Error running script: Error compiling expression 'troll': Unknown object or variable 'troll'

You don't have a troll object in your game, if you add one this should work.
