I keep running into this:

Bummer! Hmmm. It doesn't look like you're storing the returned value in the echo variable.

Hi, Val!

You're so close! It's all in the wording:

After your newly created returnValue function, create a new variable named echo.

Extract your variable declaration to be outside of the function, and assign your last line to it (e.g. var someVar = functionCall(arg);). This effectively stores the return value in your variable for later use.

Hope this hint helps!

Hi Rich,

I think I am trying your way but I'm still getting an error. Could you write out the code?

Sure thing.

Spoiler

function returnValue(age) {
  return age;
}

var echo = returnValue('15');
