private message pop-up

[Slapyo]

So far i have this:

	chdir("./forums/");
	require_once("./global.php");
	chdir("../");

	if (($bbuserinfo['pmpopup']) && ($bbuserinfo['pmunread'] > 0)) {
		echo "<script type=\"text/javascript\">";
		echo "	confirm(\"You have a new PM from $newpm[username] ... it's called $newpm[title]\");";
		echo "</script>";
	}

The pop up works if you have a new PM, but it doesn't display the username and title of the PM. Is there a variable that stores this information? I am currently looking through the different portals to see what they have and haven't figured it out.
