HTML tags not working in Dynamic TextBox

Hey,

Do you know why the tags don’t work in this text box that I’m trying to modify? However, they work if I use the preset [URL=http://nick.thedvn.com/gbv2.swf]“Text Area” component that comes with Flash. I’m following a tutorial for guestbook from flash.db.com which I combined with some php scripts to update a newsbox. Any tips are greatly appreciated.

PS. I did check off the “render as HTML” box.
