# --description--

Now your `update` function needs to use the argument you pass into it.

Inside the `update` function, change the value of the `button1.innerText` assignment to be `location["button text"]`. That way, you use bracket notation to get the `button text` property of the `location` object passed into the function.

# --hints--

Your `update` function should use bracket notation to get the `button text` property of the `location` object passed into the function.

```js
assert.match(update.toString(), /location[('|")button text\1]/);
```

You should assign the value of the `button text` property of the `location` object to the `innerText` property of `button1`.

```js
assert.match(update.toString(), /button1\.innerText\s*=\s*location\[('|")button text\1\]/);
```
