I do not understand what else I could do.

section.addEventListener('click', (e) => { if (e.target.TagName === 'INPUT') { e.target.style.backgroundColor = 'rgb(255, 255, 0)'; } });

app.js
let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if (e.target.TagName === 'INPUT') { 
    e.target.style.backgroundColor = 'rgb(255, 255, 0)';
  }
  });

It's just a spelling error (typo). This code has "TagName" (with a capital "T"), but the actual property is "tagName" (with lower case "t").
