The challenge says to create the echo variable after the function.

It looks like you created it inside the function.

Also, it says to call your function using a string argument (a string would be enclosed in quotes). Then you would assign the result to your new variable.

Echo variable must be outside of function, like this:

function returnValue(x) {
  return x;
}

var echo = returnValue('What\'s up');
