What am I missing here?

What am I missing?

function max(numberOne, numberTwo) {
  if (numberOne > numberTwo) {
    return numberOne

max(2, 1);

Right now the function is only returning something if numberOne is greater and will return nothing if it is not. Try adding an else statement returning numberTwo just in case it is greater than numberOne.

Hey Peter,

You'll need to use an else clause in case the second argument is greater than the first.

function max(foo1, foo2) {
  if ( foo1 > foo2 ) {
    return foo1;
  } else {
    return foo2;

You can be even more specific and add an else if in case foo1 is equal to foo2.
