5,151 PointsStuck on Challenge Question
The Challenge question says: Select the second SPAN element on the page and assign it to the variable lastName on line 2. Take a look in the index.html to see the structure of the document.
app.js: var fullName = document.getElementById("full_name"); var lastName;
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>
var fullName;
var lastName;
<!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>

There are a couple ways to go about this. Similar to the first challenge, you'll need to assign an element to the lastName variable.
// the second span has a class name of last_name. even though there's only one matching element,
// an array is returned unless you specify the index of the element in the array you want.
document.getElementsByClassName("last_name")[0];
//or
// there are two spans in the document. need the second one
document.getElementsByTagName("span")[1];

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

5,151 PointsThanks. I actually thought of that answer and thought that it couldn't possibly be it. The other answer you put getElementsByClassName I actually tried and it didn't go thru

Courses Plus Student 16,352 PointsThat's odd, because that's the one I used to complete the challenge. I'll double check it.
Edit: this works for me
var fullName = document.getElementById("full_name");
var lastName = document.getElementsByClassName("last_name")[0];
