I cant get my code to add the number of correct answers, it always says zero

Question

/*

Store correct answers
- When quiz begins, no answers are correct */ let CorrectAnswer = ;

// 2. Store the rank of a player let rank;

// 3. Select the <main> HTML element const main = document.querySelector('main');

/*

Ask at least 5 questions
- Store each answer in a variable
- Keep track of the number of correct answers

/*

Rank player based on number of correct answers
- 5 correct = Gold
- 3-4 correct = Silver
- 1-2 correct = Bronze
- 0 correct = No crown */ const FirstQuestion = prompt("What is my first name"); if (FirstQuestion.toUpperCase === 'RODRIGO'){ CorrectAnswer += 1; } const SecondQuestion = prompt("What is my second name"); if (SecondQuestion.toUpperCase === 'ALONSO'){ CorrectAnswer += 1; } const ThirdQuestion = prompt("What is my first last name"); if (ThirdQuestion.toUpperCase === 'GUERRERO'){ CorrectAnswer += 1; } const FourthQuestion = prompt("What is my second last name"); if (FourthQuestion.toUpperCase === 'PAQUOT'){ CorrectAnswer += 1; } const FifthQuestion = prompt("What is my age"); if (FifthQuestion === 23){ CorrectAnswer += 1; }

if(CorrectAnswer === 5){ rank = "Gold"; } else if (CorrectAnswer >= 3){ rank = "Silver"; } else if (CorrectAnswer >= 2){ rank = "Bronze"; } else { rank = "None"; }

// 6. Output results to the <main> element

main.innerHTML = <h2> You guessed ${CorrectAnswer} out of 5 </h2> <h1> You have received the ${rank} Crown </h1>;

HI Rodrigo!

You are very close, but there are a few issues:

1) You never initialized CorrectAnswer.

Use this:

let CorrectAnswer = 0; // Step 1

2) In all your if statements use FirstQuestion.twoUpperCase() // It's a function, not a property (and SecondQuestion.twoUpperCase(), etc...)

(For the fifth answer use '23' - prompt returns a string.)

Or use if (parseInt(FifthQuestion) === 23) { //Do stufff }

3) Clean up the main.innerHTML statement...

This works:

main.innerHTML = `<h1> You guessed ${CorrectAnswer} out of 5<br />You have received the ${rank} Crown </h1>`;

Note: for a temperate literal, you need the backticks

Copy this:

<!DOCTYPE html>
<html>
<body>

<main></main>

<script>
/*

Store correct answers
When quiz begins, no answers are correct */
let CorrectAnswer = 0;
// 2. Store the rank of a player let rank;

// 3. Select the <main> HTML element
const main = document.querySelector('main');

/*

const FirstQuestion = prompt("What is my first name");
console.log(FirstQuestion);
if (FirstQuestion.toUpperCase() === 'RODRIGO'){ CorrectAnswer += 1; }
console.log(CorrectAnswer);

const SecondQuestion = prompt("What is my second name");
if (SecondQuestion.toUpperCase() === 'ALONSO'){ CorrectAnswer += 1; }
console.log(CorrectAnswer);

const ThirdQuestion = prompt("What is my first last name");
if (ThirdQuestion.toUpperCase() === 'GUERRERO'){ CorrectAnswer += 1; }
console.log(CorrectAnswer);

const FourthQuestion = prompt("What is my second last name");
if (FourthQuestion.toUpperCase() === 'PAQUOT'){ CorrectAnswer += 1; }
console.log(CorrectAnswer);

const FifthQuestion = prompt("What is my age");
if (FifthQuestion === '23'){ CorrectAnswer += 1; }
console.log(CorrectAnswer);

if(CorrectAnswer === 5){ rank = "Gold"; } else if (CorrectAnswer >= 3){ rank = "Silver"; } else if (CorrectAnswer >= 2){ rank = "Bronze"; } else { rank = "None"; }

// 6. Output results to the <main> element

main.innerHTML = `<h2> You guessed ${CorrectAnswer} out of 5<br />You have received the ${rank} Crown </h1>`;

</script>

</body>
</html>

And run it.

I hope that helps.

Stay safe and happy coding!
