What variations have you tried? A little difficult to explain to what may have been done wrong when there is no code added by you :]

Hi Edmundo, please give more details on the issue you're having.

As a starting point I can see your Event Listener is missing it's closing tag so let's begin there.

const list = document.getElementsByTagName('ul')[0];

list.addEventListener('click', function(e) {
  if (e.target.tagName == 'BUTTON') {

  }
});
