What's wrong with this random number guessing game?

I made a random number guessing game in which you can determine the maximum value and the minimum value. I checked my entire code twice but can't seem to find a solution to why it won't work. I made this script linked to a HTML file that explains the document.getElementById("randNum").innerHTML part. I also want to say I am very new to coding so I might've overlooked something simple. Anyways, here's my code.

var max = prompt("Max guessing number?");

if (max <= 2) {
  document.getElementById("randNum").innerHTML = "Invalid entry";
} else {

  var min = prompt("Wat is het kleinste nummer dat je kan raden?");
  if (min >= (max - 1) || min <= 0) {
    document.getElementById("randNum").innerHTML = "Invalid entry";

  } else {

    number = Math.floor((Math.random() * max) + min);

    guess = prompt("What's your guess?");

    if (guess > max || guess < min) {

      document.getElementById("randNum").innerHTML = "Invalid entry";

    } else if (guess == number) {

      document.getElementById("randNum").innerHTML = "Good job! You guessed the number!";

    } else {

      document.getElementById("randNum").innerHTML = "Wrong! The answer was " + number + "!";

    }
  }
}
