hello im confused it says make sure im calling the greet function. am i calling it correctly?

I see in your comment when calling greet that you had a space between greet and your opening parenthesis

greet ('cool coders');
// The space between greet and the parenthesis is producing a syntax error I'm assuming
// Should be
greet('cool coders');
// No space

You have to use () if you want to call a function. This greet function accepts an argument val, so in order to call it you can do greet('cool coders'). If the greet function did not accept an argument then it would have just been greet(). The part that tells your program to actually run the function is having the parentheses.

Also, you have to save the function to a variable if you want to use an arrow function and call that function yourself as you are doing here.

You can save functions to variables. One way is like this:

const greet = function (val)  {
  return `Hi, ${val}!`
};

greet('cool coders');

So the final result when using an arrow function is:

const greet = (val) => {
  return `Hi, ${val}!`
};

greet('cool coders');
