    Javascript slider displaying incorrectly -Help a Noobie!

    First off, I know almost nothing about javascript, I'm just learning CSS and HTML, but a client wanted me to copy a working slider from one website to another associated clone site I'm making.

    On my own test page I got the slider working here, but when I transferred the same code to his site it doesn't work.

    The site is here.

    Per the clients requirement this site was built on the genesis framework for wordpress...

    Ummmm...when I bring up the problem page, all I see is
    Parse error: syntax error, unexpected ')' in /home/haloacer/public_html/wp-content/themes/halocorporateuniverities/functions.php on line 45
    Which of course means the problem is in PHP code and has nothing whatsoever to do with JavaScript.

    I have to say I don't think much of that slider even on your working test page: It only slides once (unless you use the manual buttons) from left to right. When it reaches the right end, it stops.

    Ugh. It should be a continuous strip, looping around forever.

    What about this?
    Code:
    <!DOCTYPE html>
    <html>
    <head>
    <style type="text/css">
    #bannerHolder {
        position: relative;
        margin-left: 100px;
        width: 900px;
        height: 100px;
        overflow: hidden;
    }
    #bannerHolder div {
        position: absolute;
        height: 100px;
        width: 20000px;
    }
    #bannerHolder div img {    
        padding-left: 20px;
    }
    </style>
    </head>
    <body>
    <div id="bannerHolder">
