I keep getting this error "The `max` function isn't returning a number." I ran this code in the console and it runs fine

Please take a look at my code and let me know if you can help.

script.js 
function max(numberOne, numberTwo) {
    var maxNumber = numberOne;
    if (parseInt(maxNumber) > parseInt(numberTwo)) {
      return (parseInt(numberOne)) + " " + 'number one is larger';
    } else {
        return (parseInt(numberTwo)) + " " + 'number two is larger';
  }
}
max(59, 99);

This is because you are just supposed to return the larger of the two numbers, you are returning a string containing the number and extra words. You just need the return the number, so this is a case of not returning the proper output.
