having difficulty modifying a method.

the current method i've placed keeps giving me syntax errors. What am i doing wrong?

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

end

Try 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

You'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
