[jQuery] Apple Style Slider - Multiple Sliders on same page question

[Dave Maharaj :: WidePixels.com]

I would like to use the apple style slider on my site. Found great tutorials
on it and have 1 working. My question is how can I  have more than 1?
 
Based on http://jqueryfordesigners.com/slider-gallery/ I set that up no
problem pulling my images from the database and so on....
 
My question is using that example I have 


<div id="container_<?php echo $set_id;?>">
...code...
</div>

<div id="container_<?php echo $set_id;?>">
...code...
</div>

<div id="container_<?php echo $set_id;?>">
...code...
</div>

The <?php echo $set_id;?> is in no order so it could be 27, 3, 84

How could I modify this script from the example to get the $set_id?

<script type="text/javascript" charset="utf-8">
        window.onload = function () {
            var container = $('div.sliderGallery');
            var ul = $('ul', container);
            
            var itemsWidth = ul.innerWidth() - container.outerWidth();
            
            $('.slider', container).slider({
                min: 0,
                max: itemsWidth,
                handle: '.handle',
                stop: function (event, ui) {
                    ul.animate({'left' : ui.value * -1}, 500);
                },
                slide: function (event, ui) {
                    ul.css('left', ui.value * -1);
                }
            });
        };
    </script>

Thanks,
 
Dave
