GPT-4o mini · Answer

The error message you're encountering, "The setText() id parameter refers to an id ('scoreLabel') which does not exist," indicates that your code is attempting to update the text of an element with the ID scoreLabel, but that element is not defined in your UI.

To address this issue, you should take the following steps:

Check the UI Design: Ensure that your user interface contains an element (like a Label or Text component) with the ID scoreLabel. This is typically done in the design interface of your application.
Create the scoreLabel Element: If it doesn't exist, you need to create it. Here’s an example of how to define a label in your pseudo-HTML or app design:
```
<label id="scoreLabel"></label>
```
Update Score Calculation Logic:
- You should ensure that the score calculation logic (calculateScore function, score updating, etc.) occurs at the correct point in your application flow, probably after the user finishes the quiz.

Here’s a refined version of how you might implement the score update logic:

var quizQuestions = [
  {question: "What is the capital of France?", answer: "Paris"},
  {question: "What year did the Titanic sink?", answer: "1912"},
  {question: "Who wrote 'Hamlet'?", answer: "Shakespeare"}
];
var correctAnswersCount = 0;

onEvent("startQuizButton", "click", function() {
  setScreen("screen2");
  displayQuestion(0); // Display first question
});

onEvent("backButtonQuizSelect", "click", function() {
  setScreen("screen1");
});

onEvent("generalKnowledgeBtn", "click", function() {
  setScreen("screen3");
});

onEvent("historyBtn", "click", function() {
  setScreen("screen3");
});

onEvent("scienceBtn", "click", function() {
  setScreen("screen3");
});

onEvent("popCultureBtn", "click", function() {
  setScreen("screen3");
});

onEvent("backbtn", "click", function() {
  setScreen("screen2");
});

// Display the question based on the current index
function displayQuestion(index) {
  if (index < quizQuestions.length) {
    var currentQuestion = quizQuestions[index].question;
    setText("questionLabel", currentQuestion); // Assume you have a questionLabel ID
  } else {
    endQuiz(); // Call to function to handle end of quiz
  }
}

// Submit answer and handle score
function submitAnswer(selectedAnswer) {
  if (selectedAnswer === quizQuestions[correctAnswersCount].answer) {
    correctAnswersCount++;
  }
  
  // Go to the next question
  displayQuestion(correctAnswersCount);
}

// Function to call when quiz ends
function endQuiz() {
  var totalQuestionsCount = quizQuestions.length;
  var userScore = calculateScore(correctAnswersCount, totalQuestionsCount);
  setText("scoreLabel", "Your score: " + userScore + "%"); // Ensure scoreLabel exists
}

// Function to calculate score
function calculateScore(correctAnswers, totalQuestions) {
  var score = 0;
  if (totalQuestions > 0) {
    score = (correctAnswers / totalQuestions) * 100;
  }
  return score;
}

Key Adjustments:

UI Component Creation: Create a UI label with the ID scoreLabel to display the score.
Descriptive Method for Displaying Questions: Implement the displayQuestion function to show questions sequentially.
Submit Answer Logic: Added a function submitAnswer to handle each answer submission and update the score.

Make sure you adjust your user interface in the appropriate design environment (if applicable) to add the necessary elements like questionLabel and scoreLabel.
