Codecademy coding challenge - JS number guesser

I started the JS number guesser exercise, but once I wrote my code, which was almost identical to the solution’s code, I am no longer able to press the guess button? Any idea why?

My code: let humanScore = 0;
let computerScore = 0;
let currentRoundNumber = 1;

// Write your code below:
const generateTarget = () => {
  return Math.floor(Math.random() * 10);
}

const compareGuesses = (humanGuess, computerGuess, targetGuess) => {
  if (Math.abs(targetGuess - humanGuess) === Math.abs(targetGuess - humanGuess)) {
    return true;
  } else if (Math.abs(targetGuess - humanGuess) > Math.abs(targetGuess - humanGuess) {
    return false;
  } else if (Math.abs(targetGUess - humanGuess) < Math.abs(targetGuess - humanGuess)) {
    return true;
  }
}

const updateScore = winner => {
  if (winner === 'human') {
    humanScore ++;
  } else if (winner === 'computer') {
    computerScore ++;
  }
}

const advanceRound = () => currentRoundNumber ++;

Have you checked the console for errors? Also please post your code using the code formatter </>
