I'm very confused on this one, and also with the video that goes along with this code challenge, I think Andrew Chalkey (Spelled his name wrong more than likely) was also confused while showing us how to do it. Help?

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

Hi Robert,

Line 5 :smiley: - so the full challenge would be:

var sayButton = document.getElementById("say");
var greeting = function() {
  alert("Hello World!");
}
sayButton.onclick = greeting;

Hi Robert,

You were close.

Your button is assigned to the variable sayButton and our function is within the variable greeting, so when we click the sayButton we want to run greeting().

We can do this by:

sayButton.onclick = greeting;

Note the lower case of onclick as opposed to onClick. In your current attempt you were trying to call an undefined item say on the function greeting (instead of the button sayButton).

Good luck, and happy coding.

I tried that, still giving me the bummer message. This needs to be on line 4, correct?
