functions

It says that I have not created a function named max and I believe I have.

script.js 
function max(a, b) {
  max = (5, 9)

  if (5 > 9) {
   return( max ) 
  } else {
   return( max ) 
  }
}

max()

You've created a function that takes two parameters - a & b. But you're trying to pass arguments inside the function. You just want to check generally which of the two parameters is the larger number. So if a > b you want to return a, otherwise return b (Keep in mind that this would also return b if they were equal).

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

Then you'd pass the arguments when you call it:

max(5, 9);

You have created a function called max. The problem is in the call. You just need to add an ' ; ' at the end. Like this:

max();

function max(a, b) {

  if (a > b) {
   return  a + " greater than " + b;
  } else {
   return  a + " not greater than " + b;
  }
}

var result = max(5, 9);
alert(result);
