I have tried use the 'case' and the 'if' methods and they don't seem to work.

What is the correct way of solving this. I have tried this over and over. and I know that what i have written should work.

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

end

Hi Jonathan,

Your example is absolutely good except second line.

It should be return true instead valid_command method or just put "true" in either way. 

def valid_command?(command)

  if (command == 'YES') || (command == "yes") || (command == "Y") || (command == "y")
    return true
  end

end

Hope that helps.
