# --description--

Now that the text on the buttons have changed, the `onclick` properties on the buttons should change. Inside the goStore function, update the `onclick` property of all three buttons. The new functions should be `buyHealth`, `buyWeapon`, and `goTown`. If you have trouble, look at how the buttons were initialized.

# --hints--

See description above for instructions.

```js
assert(
  goStore.toString().match(/button1\.onclick\s*\=\s*buyHealth\;?/) &&
    goStore.toString().match(/button2\.onclick\s*\=\s*buyWeapon\;?/) &&
    goStore.toString().match(/button3\.onclick\s*\=\s*goTown\;?/)
);
```
