last_name is not a valid tag. When using getElementsByTagName("..."); you need to select a valid HTML tag.

For example, <div>, <p>, <a> and <img> are all HTML tags. So you would select them by writing something like: document.getElementsByTagName("p"); to select all <p> tags in the document.

In this specific challenge that you're on I think you need to write is this:

document.getElementsByTagName("span")[1];

The challenge is specifically telling me to use getElementsByTagName. I assume the second index is the second span. There's not much else in the HTML file. If I try using document.getElementsById("last_name"); I get the same error message.

Here's the error message: Bummer! Try using the getElementsByTagName() method and using the second index (1).

Here's the 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>
