Certainly not correct, but am I close?

I feel like I'm getting there, but need a walk through.

script.js 
function max (7, 11) {
  return 7, 11;
if {
 11 >= 7;
}
else {
 7 >= 11; 
}
}

not far off.

Firstly your function arguments are slightly off. Currently you are passing 7 and 11 in as arguments. But to be more universal you should name these.

function max(numberOne, numberTwo){
  // i can now use numberOne and numberTwo inside the function
}

an if statement always needs a condition, then an action

if (condition){
  // action here
} else {
  // if condition false then do this
}

else does not need a condition, it will occur if the condition is false.

My final answer would be:

function max(one, two){
  if (one > two){
    return one
  } else {
    return two
  }
}

To run said function and pass in real numbers: 

max(10,100)

One nudge I'd give is to name the arguments in your function declaration; don't put actiual number values you intend to use with the function yet.

For example:

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

There are other enhancements needed, of course. something to consider; can you return comma separated values? Also, what will happen to the code I declare under my return statement? will it ever run?
