What am I doing wrong here?

Not sure what I'm doing wrong, since I formatted it the same way as the previous video did.

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

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

You mostly have it, but with two errors:

  • instead of "tagname", the property should be "tagName" (with a capital "N")
  • somehow the quotes around 'rgb(255, 255, 0)' got removed during editing

I'm assuming you don't need an answer to your other question at this point.
