You should have the HTML file link to the JavaScript file.

const script = document.querySelector('script[data-src$="script.js"]');

You should have a global variable called `price`.

price = 10;
assert.strictEqual(price, 10);
```
You should have a global variable called `cid`.
```js
cid = [];
assert.isDefined(cid);

You should have an `input` element with an `id` of `"cash"`.
