Why is it saying can't find variable: remove_me?

I double checked spelling, and it appears to be correct. I don't understand why it's saying the variable can't be found.

app.js 
var removeMe = document.querySelector('remove_me');
var parent = remove_me.parentNode;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>Parent Traversal</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <ul>
            <li>Hello</li>
            <li>Hi</li>
            <li class="remove_me">Good bye!</li>
            <li>Howdy</li>
        </ul>
        <script src="app.js"></script>
    </body>
</html>

Hi Alexandra,

In your first line your variable is named removeMe, but you’re trying to call the parentNode property on remove_me.

removeMe and remove_me are different.

Once you fix that you should be fine.
