programming flash

Hi i’m trying to display an image in action script and i don’t know what’s going on it just won’t appear.

this is my code:

headlineXML = new XML();
headlineXML.onLoad = myLoad;
headlineXML.load("headlines.xml");
function myLoad(ok) {
    if (ok == true) {
        Publish(this.firstChild);
    }
}

function Publish(HeadlineXMLNode) {
    if (HeadlineXMLNode.nodeName.toUpperCase() == "POSTDATA") {
        content = "";
        video = HeadlineXMLNode.firstChild;
        while (video != null) {
            if (video.nodeName.toUpperCase() == "VIDEO") {
                title = "";
                description = "";
                link = "";
                duration = "";
                element = video.firstChild;
                while (element != null) {
                    if (element.nodeName.toUpperCase() == "TITLE") {
                        title = element.firstChild.nodeValue;
                    }
                    if (element.nodeName.toUpperCase() == "DESCRIPTION") {
                        description = element.firstChild.nodeValue;
                    }
                    if (element.nodeName.toUpperCase() == "LINK") {
                        link = element.firstChild.nodeValue;
                    }
                    if (element.nodeName.toUpperCase() == "DURATION") {
                        duration = element.firstChild.nodeValue;
                    }
                    if (element.nodeName.toUpperCase() == "PLAYCOUNT") {
                        playcount = element.firstChild.nodeValue;
                    }
                    if (element.nodeName.toUpperCase() == "USER") {
                        user = element.firstChild.nodeValue;
                    }
                    if (element.nodeName.toUpperCase() == "THUMBNAIL") {
                        thumbnail = element.firstChild.nodeValue;
                    }
                    element = element.nextSibling;
                }
                content += "<img src="+thumbnail+"/> <font size='+2' color='#3366cc'><a href='"+link+"'>"+title+"</a></font><br>"+description+"<br>"+duration+"<br>"+playcount+"<br>"+user+"<br><br>";
                txt.htmltext=content;
            }
            video = video.nextSibling;
        }
    }
}

my XML:

<postdata>
             <video>
                    <title>Heiti myndbands 1</title>
                    <link>http://www.dv.is/divi/spila/123abc</link>
                    <description>asdf qwerty</description>
                    <duration>00:30</duration>
                    <playCount>123</playCount>
                    <user>notandi</user>
                    <thumbnail>anim.gif</thumbnail>
             </video>

                    <user>notandi</user>
                    <thumbnail>anim.gif</thumbnail>
             </video>
             <video>
                    <title>Heiti myndbands 3</title>
                    <link>http://www.dv.is/divi/spilaa/123cba</link>
                    <description>asdf qwerty</description>
                    <duration>00:30</duration>
