Center a div text on a liquid CSS

I've been working on a CSS fluid layout for my website, and I am trying to center the div that contains the copyright on the bottom of the page. For some reason, the text on the div wont center correctly, and it is driving me crazy. This is a link of what I am working on: http://fenixflame.net/Templates/New%20Classic%20Template/New%20Classic/New%20Classic.php

This is the CSS code I got:

    body {
    background-color: #484238;
    font-family: Verdana, Helvetica, Arial, sans-serif;
    font-size: 10px;
    color: #4F493D;
    padding-right: 10px;
    padding-bottom: 10px;
    padding-left: 10px;
    padding-top: 0px;
    margin-top: 0px;
}
#content-left {
    background-image: url(../../../Images/Backgrounds/Classic%20Template/border_left.gif);
    background-repeat: repeat-y;
    background-position: left top;
    margin: 0px;
}
#content-right {

    text-align: center;
    margin-left: 15%;
    width: 99%;
    margin-right: 15%;
    clear: both;
}

Btw, Im not really a web designer nor programer. Im sure you'll be able to tell that from the code.

the #footer { text-align: center; } rule is not present in the css file of the linked page. #footer is where you need text-align: center, not under #copyright.

You might be editing the wrong CSS file. Your sample web page has included the CSS file over here which does not have the CSS styles for #copyright.

Hope that helps.
