my solution works, but the tool says it doesn't

var warning = document.getElementById("makeItRed"); var button = warning; button.addEventListener("click", () => { var getButton = document.getElementById('warning'); getButton.style.backgroundColor = "red"; } );

it works, but it's not letting me pass

app.js
var warning = document.getElementById("makeItRed");
var button = warning;
button.addEventListener("click", () => {
    var getButton = document.getElementById('warning');
  getButton.style.backgroundColor = "red";
} );
index.html
<!DOCTYPE html>
<html>
    <head>
        <title>Adding an Event Listener</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div  id="warning">
            Warning: My background should be red!
        </div>
        <button id="makeItRed">Make It Red!</button>
        <script src="app.js"></script>
    </body>
</html>

You didn't follow the instructions. Any code provided needs to stay as is unless you are specifically asked to change. The first task is: Select the button with the ID makeItRed and assign it to the button variable. You have the code for this but overwrote var warning instead. It should be:

var warning = document.getElementById("warning");
var button = document.getElementById("makeItRed");

You have the second task ok.

button.addEventListener("click", () => {
} );

The third task is: in the button click handler, apply a background color of "red" to the warning div. There is no need to create a new variable. If you check the formatting you are specifically asked to use the warning div.

warning.style.backgroundColor = "red";
