Hi Karl!

Do the same with this code (it works fine):

<!DOCTYPE html>
<html>
<body>

<h1 id="myHeading">My Heading</h1>

<input type="text" id="myTextInput" />

<button id="myButton">My Button</button>

<script>
const myHeading = document.getElementById('myHeading');
// myHeading.addEventListener('click', () => { myHeading.style.color ='red' });

const myButton = document.getElementById('myButton');
const myTextInput = document.getElementById('myTextInput');

myButton.addEventListener('click', () => { myHeading.style.color = myTextInput.value; });
</script>

</body>
</html>

Paste it here and run it and click the button (after typing "Purple" in the text box):

I hope that helps.

Stay safe and happy coding!
