# --description--
Now add a line that updates the text of `button2` to say `Buy weapon (30 gold)` and update the text of `button3` to say `Go to town square`.
# --hints--
You should use dot notation to access the `innerText` property of `button2`.
```js
assert.match(code, /button2\.innerText/);
```
You should not use `let` or `const` to access the `innerText` property of `button2`.
```js
assert.notMatch(code, /(let|const)\s+button2.innerText/);
```
You should update the `innerText` property of `button2` to be `Buy weapon (30 gold)`.
```js
assert.match(code, /button2\.innerText\s*=\s*('|")Buy weapon \(30 gold\)\1/);
```
You should update the `innerText` property within your `goStore` function.
```js
assert.match(goStore.toString(), /button2\.innerText\s*=\s*('|")Buy weapon \(30 gold\)\1/);
```
You should use dot notation to access the `innerText` property of `button3`.
```js
assert.match(code, /button3\.innerText/);
```
You should not use `let` or `const` to access the `innerText` property of `button3`.
```js
assert.notMatch(code, /(let|const)\s+button3.innerText/);
```
You should update the `innerText` property of `button3` to be `Go to town square`.
```js
assert.match(code, /button3\.innerText\s*=\s*('|")Go to town square\1/);
```
You should update the `innerText` property within your `goStore` function.
```js
assert.match(goStore.toString(), /button3\.innerText\s*=\s*('|")Go to town square\1/);
```
