Here's what they're asking you to do. Create a function named returnValue that takes any string. Immediately return the string. Call/execute/invoke the function and pass it a string. The variable echo doesn't need to be defined inside the function. You're going to take the string returned by echo and assign it to the variable echo outside the function. Take a look at my code.

function returnValue (x) {
  return x;
}

var echo = returnValue("Hi there!  This can be anything!");
