    resolved [RESOLVED] Allow two attempts at a question (JS quiz)

    I was looking for a way in which to allow someone to have two attempts at a question in a JS quiz, and found this old thread: http://www.webdeveloper.com/forum/sh...ith-short-quiz which was posted over a year ago, with it ending with the issue that the user that two "lives" overall rather than two attempts at a question, and no response. The code is below:
    PHP Code:
    var total 3
    var 
    score 0
    var 
    correct 1

    //array list with questions & answers 
    var questions = [ 
        [
    'What is the capital of England?''London'],   
        [
    'What is the capital of Scotland?''Edinburgh'], 
        [
    'What do you call a baby cat?''Kitten'
    ]; 
    function 
    askQuestion(question//calling the function 


        var 
    answer prompt(question[0], ""); //using prompt to pull question from array and assing users answer to var 
            
    if (answer == question[1]) //if statement checking if answer = answer pulled from array list 
            

                
    alert("Correct! " "You have scored " correct " out of " total); 
                
    score++; 
                
    correct++ 
            } 
            else 
            { 
                
    alert("Sorry. The correct answer is " question[1]); 
            } 


    for (var 
    0questions.lengthi++) // counter which will end loop after 3 questions answered.  


    askQuestion(questions[i]); // indexing the array for the next question to be pulled 


    document.writeln("Well done! Your final score is " score " out of " total); 
    So rather than posting on a dead thread, I'm hoping that one of you can help me out- should be an easy fix. Thanks!
