Hi srigopi111,

I have gone through the code and its seems to bit difficult to get the correct reault using javascript and lot of workaround need to be done so better to use jQuery for generating the Results.

I have created a sample which full fill your requirement.

        "correct": 0
    },
   {
       "question": "What does 2+2 equal to?",
       "choice": ["3", "2", "4"],  //quizObj[2].choice[0],quizObj[2].choice[1]

    {
