Okay for whatever reason I cannot get this thing to work for me. I changed the Advanced Layout to read
<!--System:Shoutbox-->

and in the css file i've got this
/* This is the Shoutbox style */
.shoutbox{
overflow:auto;
height: 600px;
font-weight:normal;
font-size: 7.5pt;
}

What am I missing? I've reloaded my brower even closed and restarted. I don't know where I am going wrong.

Thanks,

If you look at your Advanced Layout Options, you'll see that your stylesheet is pointing at "style.php". This is a dynamically generated stylesheet and in general should not be directly linked to.

Modify your layout file and point your CSS file to "http://dkpfiles.com/perseid/style.css" and your changes should take effect.

Thanks Chops that did the trick
