side scrolling horizontal image gallery (multiple instances on a page) wanted

so i'm not a coder. :( i've been trying out every side scrolling piece of script i can find, but i can't get any to do what i want, exactly. basically, i have two arrows: left and right. in the middle, i have a 500px wide div with overflow:hidden, that is supposed to scroll through about 20 images.

sounds easy, right? but the layout i have calls for this to be repeated in three rows on the same page. basically, three different galleries but with the same layout of left/right arrows and content in the middle. i tried the scrollable menu script, which is great, but doesn't seem to work when more than one is put on a page. can anyone help? i would be heavily indebted!

Maybe this is more of what you're looking for: http://www.dynamicdrive.com/dynamici...rightslide.htm
