Why do I continue to receive 'SyntaxError: Parse Error'?

Parse error means that something in your code is syntactically incorrect, which leads to JavaScript not being able to understand what you are asking it to do.

The part of your code that is syntactically incorrect is the parameters (the parts inside the parenthesis) of your function. Parameters are used to pass values into a function when it is called, they are essentially variables that are assigned a value when the function is called. As such it's invalid to use actual values like strings or numbers as a parameter. A parameter has to be a variable.

The purpose of the Max function you are asked to create is to take two numbers that are provided to it when it is called, and then actually determine which one of those numbers are the largest through code, and return the number based on that. You can't just provide your own numbers and then hardcode the return like you have done in your solution, that would not make for a very useful function.

The function should look like this:

function max(a, b) { // First parameter is a, second is b.
  // a and b will now exist as variables within your function.
  if(a > b) { // So you can use them in your comparison
    return a; // If a is the greatest then return it.
  } else {
    return b; // If a is not the greatest then b must be so return it.
   }
}
