[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: [URL=”http://www.webdeveloper.com/forum/showthread.php?271527-Help-a-newbie-with-short-quiz”]http://www.webdeveloper.com/forum/showthread.php?271527-Help-a-newbie-with-short-quiz[/URL] 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:

[code=php]
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 i = 0; i < questions.length; i++) // 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);
[/code]

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!
