Stuck with conditional statements inside a function with numbers challenge task 1 of 2

can't seem to quite understand what I'm doing wrong here? Maybe I'm not understanding the way they're phrasing the question. Can someone explain to me what I'm doing wrong please?

script.js 
function max(2, 9) {
  if(9 > 2) {
    return 9;
  } else {
    return 2;
  }

Variable names cannot be numbers. You need to change 9 and 2 to valid variable names, for example: you could use num1, num2 instead.

So what ever you add as the arguments become a variable?

There are two problems here. Number one, you're missing the ending closed curly brace for your function. Number two, your code must be more generic. You are hard-coding the values.

:information_source: The guys and gals at Treehouse are going to send (possibly multiple times) different numbers to your function to make sure that what you return is what it should return. But we have NO idea which numbers they're going to send. So we use variables to (aka parameters) to sort of "catch" whatever they're sending. Take a look:

function max(a, b) {
  if(a > b) {
    return a;
  } else {
    return b;
  }
}

Yes, when you create a function, whatever you set as the parameters are automatically declared as variables inside that function.

like so:

function myNewFunction (parameter1, parameter2) {
return parameter1 +parameter2;
}
