Okay, seriously...can someone break this one down for me Barney Style...lots of pictures please

I keep getting task 1 is no longer complete. I've tried this one with letters (a, b), numbers (10, 12), and now combinations (num1, num2). The first part seems to work but I lose it when I add the alert.

script.js 
function max (num1, num2) {
  if (num1 > num2) {
    return num1;
  } else {
    return num2;
  }
}

alert(max(num1, num2) );

When you set the function up you told it to expect t20 inputs when called (num1, num2). Initially num1 and num2 are unknown so are undefined. When you call the max function, in this case you need to provide it actual data to compare. Keep in mind that functions can also call strings and other functions as well. It's a little confusing at first, but as you work your way through the course you'll get the hang of it. This is what the challenge is looking for:

function max (num1, num2) {
  if (num1 > num2) {
    return num1;
  }
  else {
    return num2;
  }
}

alert(max(600, 900));

Test it with different value inputs for num1 and num2
