There is still something wrong i need to have 4 questions to answer and it says error i need you to really get it right
```html
<!DOCTYPE html>
<html>
<head>
<script>
var tries = 0;
function checkAnswer() {
var answer = document.getElementById('answer').value;
if (answer === 'correct') {
document.getElementById('result').innerHTML = 'Correct!';
document.getElementById('nextBtn').style.display = 'block';
} else {
tries++;
if (tries < 2) {
document.getElementById('result').innerHTML = 'Try again';
} else {
document.getElementById('result').innerHTML = 'The correct answer is: correct';
document.getElementById('nextBtn').style.display = 'block';
}
}
}
function next() {
// Logic for moving on to the next question
}
</script>
</head>
<body>
<input type="text" id="answer">
<button onclick="checkAnswer()">Submit</button>
<p id="result"></p>
<button id="nextBtn" style="display: none;" onclick="next()">Next</button>
</body>
</html>
```
In this code snippet, the error is that the `next()` function is empty. It needs to have content inside the function to handle the logic for moving on to the next question.
Here is an example of how you can modify the `next()` function to address the issue:
```javascript
function next() {
// Clear the input field and result message
document.getElementById('answer').value = "";
document.getElementById('result').innerHTML = "";
// Hide the next button again
document.getElementById('nextBtn').style.display = 'none';
}
```
By adding this content to the `next()` function, you will no longer encounter an error when clicking the "Next" button after answering a question.
