You set the width and height of the divs inside the style tag, you only have to
change the divScrollTextCont, Remember to set the clip the same as the width and height.
You can remove the divUp and divDown layers if you want.
This script should also work if you make the divScrollTextCont position:relative.
Then you should be able to place this inside a table or something. Just remember
that Netscape crash very easily with relative positioned divs and tables.
Updated with a fix for error if moving over layer before pageload.

Multiple Scripts
If you have two or more scripts that use the onload event, probably only one will run (the last one).
Here is a solution for starting multiple scripts onload:
1. Delete or comment out all the onload assignments, onload=initScroll and things like that.
2. Put the onload assignments in the body tag like in this example, note that they must have braces ().
Example: <body onload="initScroll(); initTooltips(); initMenu();">
