I don't understand this question

I don't understand what the question wants me to do... How I understand it is that it wants me to make a function that returns its argument. It wants me to make a variable to hold whatever the function spits back out as a string. Am I supposed to call the function then gather what the function returns? How do I do that? Here is my code so far.

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

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

<body>
<script src="script.js"></script>

</html>

As you say, you basically just have to call the function and then save the return value in a variable. So it should look like this

var echo = returnValue("some string");
