Need help with this task

I don't understand this part of the challenge. I have tried this many ways with no success. Anyone have any pointers?

script.js 
function returnValue(width) {
  return width;
}
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi,

the challenge is asking you to store your new function inside a variable named echo. And then pass a string as value of the function.

Here's what you need:

script.js 
function returnValue(arg) {
    return arg;
}

var echo = returnValue("your string");

Thank you so much. I was making this much more difficult than it needed to be.

Like the task says "This isn't that useful of a function" it's just for you to understand how you can pass an argument to a function. In the next step of the task it asks you to assign the returned value from the function to a newly created variable called "echo". Like this:

function returnValue(width) {
  return width;
}

var echo = returnValue("Anything");

I hope that helps you a little bit.
