Can only get 0 crowns

In the quiz assignment I can only get it so that I achieve 0 crowns and I'm not sure how. I have gone over the code many times and have even simplified it to 3 questions from 5. Can anyone help? My code is pasted below

var correct = 0; //var answerOne = false; var answer1 = prompt("What color is a banana?"); if (answer1.toUpperCase === 'YELLOW') { //var answerOne = true; correct += 1; }

var answer2 = prompt("Bangkok is the capital of what country?"); if (answer2.toUpperCase === 'THAILAND') { correct += 1; }

var answer3 = prompt("What is the capital of America?"); if (answer3.toUpperCase === 'Washington') { correct += 1; }

document.write("<p>You got " + correct + " out of 3 questions correct.<p>");

if ( correct === 3 ) { document.write("You get a gold crown!"); } else if ( correct >= 2 ) { document.write("You get a silver crown!"); } else if ( correct >= 1 ) { document.write("You get a bronze crown!"); } else { document.write("Sorry, you get no crown!"); }
