```JavaScript
var echo = returnValue(hello);
function returnValue(hello) {
    return hello + "How are you?";
}

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

The problem is you're passing as an argument to the returnValue function a variable called hello that doesn't exists. I think what you want is to pass the string "hello" instead of a hello variable:

var echo = returnValue("hello");
function returnValue(hello) {
    return hello;
}

The code above passes the challenge. I hope it helps.

Many thanks.

Hi,

I hope the following helps.

To complete the challenge, the function returnValue must return just the argument passed to the function. You return:

return hello + "How are you?";

instead of:

return hello;

Calling the function is not neccesary to complete the challenge. However when you do so, you pass to the function a hello identifier (variable name) that does not exits (I think what you wanted to pass was the string "hello" instead of a hello identifier):

var echo = returnValue(hello);

But, in order to complete the challenge, only the following code is needed in script.js:

function returnValue(hello) {
    return hello;
}

Many thanks. Have a nice day,

Thanks for your help tried the solution you provided like this:

var echo = returnValue(hello);
function returnValue(hello) {
    return hello;
}

Still ain't working! What might be the problem?
