I can't do the second part of this I don't know where I'msuppsed to put the variable echo and how to call it :(

Now that you've created the returnValue function, call it, by passing it a literal string value -- a series of characters in quote marks like this: 'My argument'. Store the results of the function in a variable named echo.

I can only get the first part done.

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

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

</html>

Hey Erika,

The 2nd task wants you to set the value returned from returnValue() into the variable echo. That means all you need to do is create the variable echo and set it equal to the function call with whatever data you want like so:

function returnValue(height) {
return height;
}
var echo = returnValue("12ft");

I know what you mean, and that's why we're here to help! ^_^ Happy coding!

For setting the variable echo do; var echo = "My Argument"; then to print the variable for instance do: print(echo);
