6,992 PointsMy .addEventListener is returning null. I cant figure out why.
Here's the code I copied from the video maybe I looked over something but I get an error in the console saying my .addEventListiner cannot read properties of null.
const btnUpdate = document.querySelector ('.btn-main');
btnUpdate.addEventListener('click', () => {
const headline = document.getElementById ('headline');
const input = document.querySelector ('.input-main');
headlin.textContent = input.value });

to headline.textContent

6,992 PointsThat was definitely a part of it Thank you! The other error I noticed, and maybe it was something I missed in a previous lesson but in the btnUpdate variable they told us to link it to the class ('.btn-main') but when I checked the index the button element didn't have a class attribute so I ended up changing it to the ID attribute ('#btn-main'). I don't know if this was a mistake in the class or if I just missed something but it took me a few min to figure it out,

7,660 PointsSame thing just happened to me. btn-main was the id of that <button> instead of a class. I could have missed that being changed in a previous lesson too.
