I'm appending this element in the test and it's showing up in the preview yet it's saying my answer is wrong. Why?

This is kind of getting aggravating. I'm trying to add an element with this quiz and in the preview the element that I'm supposed to append shows up, yet, my answer continues to return as wrong. Am I missing something?

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
</head>
<body>
    <h2>Student List</h2>

    <ul class="student-list">
        <li>James McAvoy</li>
        <li>Alena Holligan</li>
        <li>Wade Christensen</li>
        <li>Matt Krzyzynski</li>
    </ul>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
$('.student-list').append("<li>Sam Smith</li>");

The challenge wants you to use the variable that you created in task 1, and append that. You have essentially done two steps in one with your solution, but the challenge wants to see the intermediate step still of you creating the variable.

How do I do that though?

It's just a case of breaking it down over two lines, like this:

const $newStudent = $('<li>Sam Smith</li>');  // Create new variable containing list element.
$('.student-list').append($newStudent);  // Append this element to the list.
