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 ++;
```
