HTML in text box

So I’m trying to put RSS data in a text box, with formatting to the titles and the like. I have a text box with the instance name of “aText”, and I have the ‘Render text as HTML’ checked.

aText.htmlText = "";

for each (var RSSItem:XML in aRSS) {
    aText.appendText("<b><a href = " + aRSSLinks* + ">");
    aText.appendText(RSSTitles* + "</a></b><br />");
    aText.appendText(RSSDescriptions* + "<br />");
}

When it is displayed, all the HTML tags are displayed and nothing is formatted. It’s probably something simple, but I’m no expert at this. Thanks for the help.
