Scrollable Content II, with variable height?

[Lockerbie]

1) Script Title: Scrollable Content II

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex11/scrollc2.htm

3) Describe problem: Using this script with an iframe, you have to set a height. As I am using this for a guestbook-iframe, is it possible to use a variable height?

Sorry for the *bump*.

I found a script that doesn't need the height set, and tested it.
But what I really want, is to be able to use the two arrows for mousemovement/mouseovers, with the functionality of this other script, so that I don't have to set a height for the iframe, òr the scrollbar.
As I'm no "scripter", I can't seem to get it right...
