65,469 PointsYou're doing great! There are some exceptions, though. Firstly, remove one of the "end" keywords. That's causing the Syntax Error thing. Second, instead of doing "y, yes, Y, YES", you have to compare "command" with each of them. Also, you should use "||" for the or operators instead of ", ". Third, "return = true" is like saying "take this variable called 'result' and assign it to true", so get rid of that "=" sign. Lastly, you aren't always gonna return "true", so try returning a variable called "valid" that I have assigned. Try my code if you don't understand what I said:
def valid_command?(command)
valid = (command == "y") || (command == "yes") || (command == "Y") || (command == "YES")
return valid
end

18,425 PointsTry adding the OR operator ||
command = "y" || "yes" || "Y" || "YES"
edit: Also try using an if statement instead of just assigning command to 4 things. I.E.
IF command == "y" || <more code> return true
