A CHALLENGE...(for me)

Ok can anyone let me know how to do the following?

I need to add scrollable text to my movie, meaning a long body of text that appears in a small space with scrollbuttons on the side.

Also, the text has to have no background. Or rather, a transparent background. I need to put the text over a background that is already partly transparent, with another background behind that. Make sense? So I’ve got my movie’s background picture, then on top of that, a [75% alpha] box, and the text goes on top of that.

If all of this sounds confusing or otherwise not good…let me know, but I really could use some help on this…I’m kind of new to flash. Thanks
