Why does this not work? var lastName = document.getElementByTagName("span")[1];

Trying to select select item in array for span element. The first span element contains the first name [0]. The second span element contains the last name. It should be indexed at [1].

Is there something wrong with my syntax?

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>

Hey Sue,

This is because the command is "getElementsByTagName()". You left out an "s" on the "Element" part of the command. :)

var fullName = document.getElementById("full_name");
//Change Element to Elements
var lastName = document.getElementsByTagName("span")[1];
