Still don't know what's wrong X_X

don't know what I'm doing wrong, again...

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

    return "true"
  end

end

Hi,

Some of errors you get is because of brackets ( ) in each command that can't solve the problem. The values of yes, y, Y, YES should have double quotes that's part of strings. 

 def valid_command?(command)

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

end

You did great start, just some minor errors in syntax.

Hope that helps. ;)

Thanks again! Is it because these are string values so you need double quotes?

They can also be single quotes. The point is - without any quotes they are variable names, not strings.
