I believe in the previous video li and ul were defined in the second if statement. The new code should look like this

ul.addEventListener('click', (e) => {
    if (e.target.tagName === 'BUTTON') {
        const button = e.target;
        const li = e.target.parentNode;
        const ul = li.parentNode;
        if (button.textContent === 'remove') {
            ul.removeChild(li);
        } else if (button.textContent === 'edit') {
            const span = li.firstElementChild;
            const input = document.createElement('input');
            input.type = 'text';
            li.insertBefore(input, span);
            li.removeChild(span);
        }
    }
}); ```

Maybe it really was never defined. We'd need to see all the code to tell.

The best way to share an entire project is to make a snapshot of your workspace and post the link to it here.
