The conditional challenge

I don't know why at the end of this challenge even with 5 correct answers i'll still get 3 out of 5? I think something is wrong w output rank but i can't figure out . Thanks

// quiz begins, no answers correct var correct = 0;

var answer1 = prompt("Who was the first American in space?"); if (answer1.toUpperCase() === "ALAN SHEPARD" ) { correct += 1; } var answer2 = prompt("Who was the first president of United state?"); if (answer2.toUpperCase() === "GEORGE WASHINGTON" ) { correct += 1; } var answer3 = prompt("What was the first American car company?"); if (answer3.toUpperCase() === "FORD" ) { correct += 1; } var answer4 = prompt("What was the very first restaurant in America?"); if (answer4.toUpperCase === "DELMONICO") { correct += 1; } var answer5 = prompt("What was the very first war in America?"); if (answer5.toUpperCase === "AMERICAN WAR OF INDEPENDENCE" ) { correct += 1; } //Output results document.write("<p>You got " + correct + " out of 5 questions correct.</p>");

// Output rank if (correct === 5 ) { document.write("<p><strong>You earned a gold crown.</strong></p>"); } else if (correct === 3) { document.write("<p><strong>You earned a silver crown.</strong></p>"); } else if (correct === 2) { document.write("<p><strong>You earned bronze crown.</strong></p>"); } else { document.write("<p><strong>No crown for you.</strong></p>"); }
