# --description--

After a user makes a selection, they should be able to keep that score and move onto the next round by clicking the `keepScoreBtn`.

When that button is clicked, you should find which radio option is checked and capture its value and id attributes. If the user has selected an option, call your functions to update the score, reset the radio options, and add the value and id to the score history.

If the user has not selected an option, display an alert informing them to do so.

# --hints--

When your `keepScoreBtn` is clicked, the score should be updated in the `totalScoreElement` text.

```js
scoreInputs[0].checked = true;
scoreInputs[0].value = "10";
score = 10;
keepScoreBtn.click();
assert.strictEqual(totalScoreElement.innerText, "20");
```

When your `keepScoreBtn` is clicked, the radio options should be reset.

```js
scoreInputs[0].checked = true;
scoreInputs[0].value = "10";
score = 10;
keepScoreBtn.click();
for (const element of scoreInputs) {
  assert.isFalse(element.checked);
  assert.isTrue(element.disabled);
}
for (const element of scoreSpans) {
  assert.strictEqual(element.innerText, "");
}
```

When your `keepScoreBtn` is clicked, the score history should be updated.

```js
scoreInputs[0].checked = true;
scoreInputs[0].value = "10";
scoreHistory.innerHTML = "";
keepScoreBtn.click();
assert.strictEqual(scoreHistory.innerHTML, "<li>three-of-a-kind : 10</li>");
```

When your `keepScoreBtn` is clicked, and no options are selected, you should display an alert to the user.

```js
const messages = []
const oldAlert = alert;
alert = (msg) => {messages.push(msg)};
const oldWindow = window.alert;
window.alert = (msg) => {messages.push(msg)};
keepScoreBtn.click();
assert.lengthOf(messages, 1);
```
