Correct and incorrect answers are not summing properly

Im having trouble getting the right and wrong answers to sum correctly in the string literal. I've instantiated the variables in many different spots in the code but none of them seem to work. The console.log(right / wrong) checks below the loop are generating the correct value. Any help would be appreciated!

Thanks, Gary

let right = 0
let wrong = 0

let questionPairs = [
  ["What color is Butters?", "brown"],
  ["What language is this?", "javascript"],
  ["What game is Colleen playing?", "jeopardy"]
];

function print(message) {
  document.write(message);
}

listHTMLright = `<h1>You got ${right} questions correct, they were: </h1>` //cant get ${} to generate the correct number
listHTMLwrong = `<h1>You got ${wrong} questions incorrect, they were: </h1>` //cant get ${} to generate the correct number

for ( i = 0; i < questionPairs.length; i += 1 ) {
  questionAnswer = prompt(questionPairs[i][0]).toLowerCase()
  if ( questionAnswer === questionPairs[i][1]) {
    listHTMLright += `<li>${questionPairs[i][0]}</li>`;
    right += 1
  } else {
    listHTMLwrong += `<li>${questionPairs[i][0]}</li>`;
    wrong += 1    
  }
}

console.log(right) //check that right is the correct value
console.log(wrong) //check that wrong is the correct value

combined = listHTMLright + listHTMLwrong;

print(combined)

The message strings "listHTMLright" and "listHTMLwrong" are both being assigned before the questions are asked, when the scores are zero.

To show correct scores, the total messages would need to be added after the question loop, near where the log messages are done.
