Custom Private Message Popup (Need help)

[Eplexx]

Note: I posted this in the wrong section, I'm trying to design and program this for vb3.

I'm trying to program this popup message system to vbulletin. Upon a new private message received it'll popup with:



and show the title of the private message and the message.

I'm using js here is my code:

<script type="text/javascript">
function showMessageWithoutImage() {
		$.jnotify(
			'$pm[title]', 
			'$newpm[title]'
		);
	}
</script>

I'm not sure what's the proper private message variables or how to do it as this is my first time messing with the popup private message stuff. Anyway is anyone able to help me?
