Not Work

Hello guys, I can not complete this operation because the system tells me that there is an error, but I'm sure the code is correct. Is it a bug?

app.js 
var sayButton = document.getElementById("say");
var greeting = function() {
  alert("Hello World!");
  sayButton.onclick  =  greeting;
}
index.html 
<!DOCTYPE html>
<html>
<head></head>
<body>
<button id="say">Say "Hello World!"</button>
<script src="app.js"></script>
</body>
</html>

Fixed. My mistake .. the line of code was placed after the brackets, on line 5, but I'd written inside. ;)

super close, Fabio!

You've got the correct code, but it's currently inside the greeting function. If you move it outside the greeting function, it should work!

edit: and i see you figured it out already, nice!

Hi fabio you should call sayButton.onclick = greeting; outside of your function and it should work:)
