Javascript single to multiple instances

Hi,
I have the attached code.  It scrolls text horizontal to create a marquee.  The original version will only scroll one string of text per page since its using getElementById.  How can I make it scroll any number of elements?  The snippet that actually holds the text to be scrolled is this:

<div id="marqueecontainer">
<span id="vmarquee" style="position: absolute; width: 98%;"><nobr>
TEXT TO SCROLL HERE
</nobr></span>
<span id="vmarquee2" style="position: absolute; width: 98%;"></span>
</div>

Thanks,

<style type="text/css">
 
#marqueecontainer{
position: relative;
width: 100px%; /*marquee width */
height: 15px; /*marquee height */
 
color:#4a4a4a;
overflow: hidden;
border: none;
padding: 1px;
 
text-align:left;
font-size:11px;
}
 
 
</style>
