Please help me understand...

I've tried several things, even putting the 'greetings' parameter into the echo variable, but it's not working out. That, and I don't really understand the question. The way it's worded is screwing me up but I can't explain why. And I believe I've tried writing - return echo + greeting; but that isn't working either.

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

Hi Christopher Since you need to assign echo variable to the return value of the returnValue function, the echo variable should be initialized after the function definition, not in the function itself. You can do this as follows: var echo = returnValue("some string");

Thanks Valentin

I guess I wasn't understanding that the question was asking you to put the variable outside of the initial function's code block.

Appreciate the help :)
