A share in facebook question

Guys...

I was looking for a way to share in facebook a score a user can make playing a game...

I found this website: http://www.actionscript.org/resources/blogs/52/Facebook-and-Twitter-buttons-in-Flash-and-Flex.html so I went ahead and copied the code, modified it and placed in my actionscript...

However it shares the webpage I put in the link, but it does not put the text...and, also, what I would like it to say is something like: Can you beat my score of (count)? ...

Now, is it possible with something like this? What should I add?

Here is the code: (count is the var where I have the score made in the game)

if (espanol) addChild(botonface);

if (ingles) addChild(btnface);

btnface.addEventListener(MouseEvent.CLICK, goFace);

botonface.addEventListener(MouseEvent.CLICK, goFace);

function goFace(e:MouseEvent):void {

    btnface.removeEventListener(MouseEvent.CLICK, goFace);

    botonface.removeEventListener(MouseEvent.CLICK, goFace);

    socialUpdate("facebook", "Can you beat my score", "www.google.com");

}

function socialUpdate(site:String, text1:String = "",  link:String = "")

{

    var siteURL:String;

    var maxLength:Number;

    switch (site) {

        case "facebook":

        maxLength = 255;

        break;

        default:

        return;

        break;

    }

    var availableTextLength:Number = maxLength - (link.length + 1);

    if (text1.length > availableTextLength) {

        text1 = text1.substr(0, (availableTextLength - 3)) + '...';

    }  

    switch (site) {

        case "facebook":

        siteURL = "http://www.facebook.com/share.php?u=" + encodeURIComponent(link) + "&t=" + encodeURIComponent(text1);

        break;

    }

    var urlRequest:URLRequest = new URLRequest(siteURL);

    navigateToURL(urlRequest, "_blank");

}
