code challenge problem

I am having trouble with the following code challenge.

Create a new function named max() which accepts two numbers as arguments. The function should return the larger of the two numbers. You'll need to use a conditional statement to test the 2 numbers to see which is the larger of the two.

script.js 
function max(100, 50) {
  if (100 > 50) {
    document.write("100");
  } else {
    document.write("50");
  }
}

Your code is mostly fine, but to make it into an actual function that takes any two numbers, you'll need to use variables rather than actual numbers. You'll also need to parse the input of those variables into integers using the parseInt() function. I'd revise your code to something like this:

function max(num_1, num_2) {
  var number_1 = parseInt(num_1);
  var number_2 = parseInt(num_2);
  if (number_1 > number_2) {
    document.write(number_1);
  } else {
    document.write(number_2);
  }
}

Keep in mind, you'll also need a way of capturing input, but you can do that with prompt() calls like you've been using so far, or even run it in the console using max(x,y); replacing x and y with actual numbers.
