Move this function to below the definiton of elevator
elevators don't yet exist. Read top to bottom, that's the way the compiler
does it.

move this function to below the definition of elevator. You are trying to
destroy something which doesn't yet exist.

if you want your elevator to have buttons, this is probably the place to
generate them.

You have written too much code without doing any testing. Please pay
attention.
