iFrame Scroller - how can I make the frame transparent?

[slsmag]

Script Title:
iFrame Scroller

Script URL (on DD):
dynamicdrive.com/dynamicindex2/iframe-scroller.htm

The Problem:

No matter what I do I can't get the iframe to appear with a transparent background.

Is there a way to accomplish a transparent background in an iFrame?

My iFrame is contained in a regualr frame (if that makes any differnece) and can be viewed here: 4inHomeCare.com

I have tried adding a style to the body tag of the external file and fiddling with the script call in the main html - all to no avail.

Any suggestions?

Also, the script (as I have it installed: within a frame) does not work in FF 3.0.10.
