HELP - iframe scroller

[KrayZ]

Hi all,

I want to use the Iframe-scroller on the website:
http://www.dynamicdrive.com/dynamicindex2/iframe-scroller.htm

I just want to change the way of scrolling but i dunno how.
I modified the html fopr the iframe with pictures to scrol within the Iframe.
The problem which occurs is, if the scroll is above... the picture flips back... this looks awfull.

I want the scroller to scroll down if all content is above. So it would be going like this one on the left: http://www.emp.de/bin/shop.php?prog=site&article=424975&funktion=lp&LANG=DE

Can someone help me pls???

Thnx in advance
