I do not know how to make this method return true when the parameter passed in is any of the accepted inputs

ruby.rb 
def valid_command?(command)
  if (command == y) || (command == yes) || (command == Y) || (command == YES)
    return true
  end
end

If those are supposed to be string inputs, you need to put them in single or double quotes. As of right now, it looks like it thinks that command needs to be equal to four variables that you havent defined yet.

Also, if you want to make it case insensitive, you should add "command.downcase!" or "command = command.downcase" in front of the if statement.

Good luck.
