There's nothing here.
Have you tried using print instead of show?
I haven't tried it, because I'm a novice and need to consult others.
show come from though? I’ve never heard of it. Did you bring knowledge of something called “show” from a different environment? Or are you trying things out like in a text adventure? That would be an interesting take on how to program. Languages like that will certainly exist someday; do they already?
