Any idea as to why my value for answering a question correctly is not adding up?

/*

1. Store correct answers
   • When quiz begins, no answers are correct */ let correct = 0 ;

// 2. Store the rank of a player let rank = 'iron';

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

/*

1. Ask at least 5 questions
   • Store each answer in a variable
   • Keep track of the number of correct answers */ const answer1 = prompt('Is the sun a star?' ); if ( answer1.toUpperCase() === 'yes' ) { correct += 1; } const answer2 = prompt('Is grass green?'); if ( answer2.toUpperCase() === 'yes') { correct += 1; } const answer3 = prompt('Is the sky blue?'); if ( answer3.toUpperCase() === 'yes' ) { correct += 1; } const answer4 = prompt('What day is it today?'); if ( answer4.toUpperCase() === 'Monday' ) { correct += 1; } const answer5 = prompt('What color is my water bottle?'); if ( answer5.toUpperCase() === 'Black' ) { correct += 1; }

/*

1. Rank player based on number of correct answers
   • 5 correct = Gold
   • 3-4 correct = Silver
   • 1-2 correct = Bronze
   • 0 correct = No crown */ if ( correct === 5 ) { rank = "Gold"; } else if ( correct >= 3 ) { rank = "silver"; } else if ( correct >= 2 ) { rank = "Bronze"; } else { rank = "None :("; }

// 6. Output results to the <main> element main.innerHTML = <h2>You got ${correct} out of 5 qustions correct.</h2> <p>Crown earned: <strong>${rank}</strong></p> ;
