Center javascript output on sidebar?

I managed to get a “nowplaying” plugin working with my site (http://www.camiam.org)
The problem is that I can’t get the output centered on the sidebar. I’ve tried for 2+ hours and decided I’d better post before 2 hours becomes 4.

The aforementioned output is just below the red text on the sidebar.

Here’s the pertinent code:

Sidebar.php followed by the .js file:

<div id="sidebar">
<ul>
<<<snip>>>

_______________________________

<P><center><font color=red><i><B> If you had headphones plugged into my computer we'd both be listening to:</B></i></font></center></P>
<P>
<P>
<script><!--
p_playing_width=187;
p_div_width=500;
p_playing_height=35;
p_playing_border=0;
p_text_color="purple";
p_border_color="GREEN";
p_bg_color="";
p_font_color="0066ff";
tokenID="cnSsExqjwovpEAXJYhzf";
//-->
</script>
<script type="text/javascript"
src="http://www.camiam.org/nowplaying.js"></script&gt;

<<<snip>>>

And the .js file:

/*
* Playing.js for Winamp Nowplaying2Web Plugin
* xiaoyisheng@gmail.com
* See http://www.blueforge.net/playing for details
* version 0.1 2005/11/15
*/

var w=window;
var d=document;

function quoted(str) {
return (str != null) ? ‘”‘ + str + ‘”‘ : ‘””‘;
}

p_playing_url=’http://www.blueforge.net/playing/my.php’+
‘?width=’+w.p_playing_width+
‘&height=’+w.p_playing_height+
‘&fontcolor=’+w.p_font_color+
‘&bgcolor=’+w.p_bg_color+
‘&bordercolor=’+w.p_border_color+
‘&border=’+w.p_playing_border+
‘&tokenID=’+w.tokenID
;
if (w.p_div_width)
p_playing_url+=’&divwidth=’+w.p_div_width;

d.write(‘ <iframe allowtransparency=”true” background-color=”transparent” name=”now_playing_frame” vspace=”0″ hspace=”0″ width=”‘+w.p_playing_width+
‘” height=”‘+w.p_playing_height+
‘” frameborder=”‘+w.p_playing_border+
‘” marginwidth=”0″ marginheight=”0″ allowtransparency=”true”‘+
‘ scrolling=”no” src=’+quoted(p_playing_url)+’></iframe>’);
`

I moved the .js file to my site so I could edit it but my tinkering provided no progress.

Sincere thanks in advance,
