# --description--

We have run in to a slight problem. You are trying to query your page for a button element, but your `script` tag is in the `head` of your HTML. This means your code runs before the browser has finished reading the HTML, and your `document.querySelector()` will not see the button - because the browser hasn't processed it yet.
|
||
|
|
|
||
|
|
To fix this, move your `script` element out of the `head` element, and place it at the end of your `body` element (just before the closing `</body>` tag.)
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
Your `script` element should not be in your `head` element.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const script = document.querySelector('script[data-src$="script.js"]');
|
||
|
|
assert.notEqual(script.parentElement.tagName, "HEAD");
|
||
|
|
```
|
||
|
|
|
||
|
|
Your `script` element should come at the end of your `body` element.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const script = document.querySelector('script[data-src$="script.js"]');
|
||
|
|
assert.equal(script.previousElementSibling.tagName, "DIV");
|
||
|
|
assert.isNull(script.nextElementSibling);
|
||
|
|
assert.equal(script.parentElement.tagName, "BODY");
|
||
|
|
```
