Returning the largest number in the function

I am suppose to write a max function that has two arguments and those arguments are suppose to be numbers. I am suppose to return the largest of the number, however this particular function is not working. Please point me to the right direction.

script.js 
function max(upper, lower) {
  var upper = '';
  var lower = '';
  if(upper > lower) {
     return upper  
  }
}
max(3,2)

var upper = ''; var lower = ''; these are the same variable name, you are using in the argument, which got re-assigned to ''. You can use this.

function max(upper, lower) {
    return (upper>lower)? upper : lower;
}

Christopher Anderson ,

rahul saini answer is correct, however if you haven't used ternary operators before I just wanted to give you the example as a normal function. If you're all over ternary operators then disregard!

function max(upper, lower) {
  if (upper > lower) {
     return upper  
  }
     return lower; 
}
max(3,2)
