Where I am doing wrong in this quiz app? When I am running it, I get different answers. Pls guide me.

var correct = 0; var questionNumber = 5; var questionInfo = '[You have '; var userQuestionOne = prompt('Who Played Rocky in movie Rocky? ' + questionInfo + questionNumber + ' questions left]'); if (userQuestionOne.toLowerCase() === 'sylvester stallone') { correct = 1; } questionNumber -= 1; var userQuestionTwo = prompt('What is Spiderman\'s real name? ' + questionInfo + questionNumber + ' questions left]'); if (userQuestionTwo.toLowerCase() === 'peter parker') { correct = 2; } questionNumber -= 1; var userQuestionThree = prompt('Who Directs Avatar movie? ' + questionInfo + questionNumber + ' questions left]'); if (userQuestionThree.toLowerCase() === 'james cameron') { correct = 3; } if (correct >= 2 ) { alert('You got a gold crown.'); } else if (correct == 1) { alert('You got a silver crown.'); } else { alert('You score zero. Try again'); }

Abhijeet,

It looks like just a simple mistake is keeping this code from working correctly. I believe you are intending to increment the "correct" variable by 1, each time they answer a question correctly. However, your code is overwriting the value, instead.

Here's the fix (just change the three if statements as follows):

if (userQuestionOne.toLowerCase() === 'sylvester stallone') {
  correct += 1;
}

if (userQuestionTwo.toLowerCase() === 'peter parker') {
  correct += 1;
}

if (userQuestionThree.toLowerCase() === 'james cameron') {
  correct += 1;
}

This causes the "correct" variable to be incremented by 1, with each new correct answer, which will solve your issue.

I hope this helps! Happy coding :-)

Dear Tommy, Thank you for your help. Now I can understand the mistake. One question i have in my mind, that is using the correct ++ as an increment operator (++) in console, I am getting confusable outcomes like : var correct = 0; correct ++; 0 //why I am getting 0 here? should not be the var store numeric 1, instead of 0?// correct ++; 1 //here should be the var store numeric 2, instead of 1?// please help me to clear this. Thanks.

I think I made a mistake i put a space between correct and ++. So instead of correct ++, its supposed to be correct++. I hope that solves your problem.
