Chat feature for Online Multiplayer Game

Does anyone know where, or know exactly how to make a simple flash chat feature. A basic one, just inputs your name and message into a dynamic text box. I’ve looked at all the existing ones and none of them have worked exactly for me (using xml sockets).

None of these ended up working on my server. Is their a specific, complete idiot proof one that anyone knows of? Or at least a more in depth version of one of these by yourself? This has been frustrating me for at least two days… changing ports, setting my own server and one off a website to test. Any help, big or small, would be excellent.
