I don't know how to set the value of echo to be the results from calling the returnValue function.

please help

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

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

Well, just in general, to set the value of somevariable to the result of calling somefunction:

var somevariable = somefunction(arguments);

Yep. And in a sense, you can almost imagine that a function "is" the result that it returns. You may be getting hung up on the echo "the results" part of the question.

The function... returns the results. :) The function "is" the results. And Steven has provided a great template for you.
