# --description--

The `Sort` button may appear to work correctly when clicked, but this is only because all the values in the array are single digits, and the sorting may not work as expected with more complex values.

Change the `value` and text of the `option` element that is `selected` from `1` to `10`, and click the `Sort` button again.

# --hints--

You should update the `value` of the `option` element that is `selected` to `10`.

```js
const values = document.querySelectorAll('.values-dropdown')?.[3];
const option = values.querySelector('option[selected]');
assert.equal(option?.value, '10');
```

You should update the text of the `option` element that is `selected` to `10`.

```js
const values = document.querySelectorAll('.values-dropdown')?.[3];
const option = values.querySelector('option[selected]');
assert.equal(option?.textContent, '10');
```
