Need some fresh eyes... can't see my mistake. Remove button not working.

const form = document.getElementById('registrar');
const input = form.querySelector('input');
const ul = document.getElementById('invitedList');

function createLI(text) {
  const li = document.createElement('li');
  li.textContent = text;
  const label = document.createElement('label');
  label.textContent = 'Confirmed';
  const checkbox = document.createElement('input');
  checkbox.type = 'checkbox';
  label.appendChild(checkbox);
  li.appendChild(label);
  const button = document.createElement('button');
  button.textContent = 'remove';
  li.appendChild(button);
  return li;
}

form.addEventListener('submit', (e) => {
  e.preventDefault();
  const text = input.value;
  input.value = '';  
  const li = createLI(text);
  ul.appendChild(li);
});

ul.addEventListener('change', (e) => {
  const checkbox = e.target;
  const checked = checkbox.checked;
  const listItem = checkbox.parentNode.parentNode;

  if (checked) {
    listItem.className = 'responded';
  } else {
    listItem.className = '';
  }
});

ul.addEventListener('click', (e) => {
  if (e.target.tagname === 'BUTTON') {
    const li = e.target.parentNode;
    const ul = li.parentNode;
    ul.removeChild(li);
  }
});

There's a spelling error/typo where the code has "tagname" (lower case "n") instead of "tagName" (capital "N").

Thanks you so much Steven!

This is one of the many reasons working on teams is so important. I went through that code line for line and missed the mistake repeatedly. A good set of fresh eyes and bingo!

Thanks again Steven, you are a gentleman and a scholar ;)
