Hey Kwame,

It looks like the error is actually coming from your HTML. Take a look at your button element:

<button class = "desription>Change list description</button>

The class is misspelled and there isn't a set of quotes to close off the class name. The spelling doesn't actually matter in this instance since it's not being used yet, but the quotes do -- the next quotes in the document are found much later, so everything in between them has been interpreted as the class name. If you open developer tools and view the class for the button you'll see this:

desription>Change list description</button>↵↵↵↵ <ul>↵ <li>grapes</li>↵ <li>amethyst</li>↵ <li>lavender</li>↵ <li>plums</li>↵</ul>↵↵↵<script src=

Closing the quotes around your class name should get things working as expected. It's worth correcting the spelling as well, just in case that class gets used later. Hope this helps!
