You see, when you sign up with Chat Planet, an applet is created just for you. After it's created, it's placed in a directory. CODE tells the browser which file inside the directory to use. In this case I am using an applet called eweb.chat.ChatApplet.class. You have to have this.
Applets work inside their one little window.
The height and width settings define the window. Some applets allow you to change the height and width. This one does not. Go with the sizes you are sent. Now, the Applet's Parameters Immediately under the main applet command comes all the commands.
