Can someone take me through the steps of completing and understanding this challenge please?

I'm stumped on the second task.

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

var echo = returnValue(argument);
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Actually, you have it solved except for one issue. In the function, the word "argument" stands for a parameter that will be passed in. So that's perfectly fine.

But in the call on the bottom line, it causes a syntax error because it attempts to reference something that has not been defined.

So just replace the word argument on the bottom line with some literal string value, like "Howdy" or "JavaScript".

When i do that is says Task 1 is no longer correct. You are saying to do this:

function returnValue(argument) { return argument; }

var echo = returnValue("Howdy");

right?

Yes, and if I paste those lines directly into the challenge, I get a "pass" for both tasks!
