What's wrong!

What is wrong with my code?

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

Your commands should be strings. Also, you are returning a string containing the word "true" when you should be returning a boolean of true.

You need to enclose your yes values in quotes to make them strings, for example:

if (command == 'y')

You just need to put the word true with no quotes around it.

return true
