Why isn't working? var fullName = document.getElementById("full_name");

var fullName = document.getElementById("full_name"); var lastName = document.getElementByTagName("span")[1];

app.js 
var fullName = document.getElementById("full_name");
var lastName = document.getElementByTagName("span")[1];
index.html 
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 id="full_name"><span class="first_name">Andrew</span> <span class="last_name">Chalkley</span></h1>

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

You're missing an 'S' in the getElement<b>s</b>ByTagName method. This is probably causing your JS to fail.

Add that 's' in and you should be fine.
