Hello, I'm having trouble with my code for pt.2 of this task. Is "...getElementsByTagName('last_name')[1]" incorrect?

First task is passing, with "getElementById" just fine, but the second part, I'm certain that "...getElementsByTagName('last_name')[1]" is correct... am I missing something? Thanks!

app.js 
var fullName = document.getElementById('full_name');
var lastName = document.getElementsByTagName('last_name')(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 close, you want to select the span as part of getElementsByTagName:

var lastName = document.getElementsByTagName('span')(1);

Thank you! Wow, ok so the theory is instead of using the the actual name, because those are more specific, we use the tag type, followed by the index # to specify which one we want to target?

This explanation does a good job:

The getElementsByTagName() method returns a collection of an elements's child elements with the specified tag name, as a NodeList object.

The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0.
