  • The name of your parameter when you declare your function shouldn't be in quotes.
  • They want you to call this function and store the result in a variable called echo. You need to do this outside the curly braces {} of the function declaration.
function returnValue (pepe){
  return pepe;
}

var echo = returnValue("echo");
