what am i doing wrong?

it says to create a function called sayHi and not put anything inside, but to have the basic structure with an empty code block

script.js 
function sayHi(

);
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

You're missing the curly braces.

You need opening and closing parentheses AND opening and closing curly braces. Inside the parentheses is where you would put any parameters. In this case there are none but you still need the empty parentheses. Inside the curly braces is where you're going to put the things that the function does.

function sayHi() {

}

When you create a function like function sayHi(

); - You are invoking/calling a function before actually declaring it. To declare a function before calling it please use function sayHi (){

}

I hope then it should work and then you can call it as sayHi();
