Edit Button Error ...

My edit button logs error on the console stating "li is not defined" on const span=li.firstElementChild;

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.

Please show us your code so that we can better help you.

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