Challenge Task 3 of 3 Call the new sayHi function you just created.

Everytime I submit the answer to the 3rd question of this quiz I receive the "Oops, communication error". I'm almost finished with the prerequisites but am afraid I might not finish due to this error! HELP!

script.js 
function sayHi() {
  alert("Hi");

    sayHi();
}
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi Devin. The problem is that you are calling the function inside the function itself. What you should do is call it outside the function block.

function sayHi() { alert("Hi"); }

sayHi();

Yep, just figured that out and it passed. Weird that it kept making the page lose connection though, right?

Yeah. I guess there are tests in place that parses the code and makes sure the answer is correct, otherwise it throws an error.
