Hi there! throughout this course as I follow along with Guil's code, I've been getting an error on line 4 and I can't seem to figure out how it's different and where I am going wrong.
This is what my code looks like currently:
const btnToggle = document.querySelector('.btn-toggle');
const btnCreate = document.querySelector('.btn-main');
btnCreate.addEventListener('click', () => {
const input = document.querySelector('.input-main');
const item = document.createElement('li');
item.textContent = input.value;
input.value = '';
});
Thank you so much!

<button id="btn-main">Add Task</button>
This creates a button with an id instead of a class, so the query won't find it. This can be fixed in either of two ways:
- in the HTML by changing "id" to "class"
- in the JavaScript by changing the query selector from ".btn-main" (class selector) to "#btn-main" (id selector)

A much better way to share project code (all parts together) is to make a snapshot of your workspace and post the link to it here.
