Not able to get list to appear and disappear.

It was working with the previous example to hide the list. Now, I'm not able to get it to hide or show the list using the if-else statement. What am I missing or what do I have wrong?

const toggleList = document.getElementById('toggleList'); const listDiv = document.querySelector('.list');

const input = document.querySelector('input'); const p = document.querySelector('p.description'); const button = document.querySelector('button');

toggleList.addEventListener('click', () => {

if(listDiv.style.display == 'none') { toggleList.textContent = 'Hide List'; listDiv.style.display = 'block; } else { toggleList.textContent = 'Show List'; listDiv.style.display = 'none'; } });

button.addEventListener('click', () => { p.textContent = input.value + ':'; });

p.title = 'List description';

To make future code postings easier to read, always use Markdown formatting, or share the entire workspace by making a snapshot and posting the link to it.

But it looks like the problem here might be a missing quote after the the word "block' (right before the "else").

Thanks! I'll use the markdown here on out.
