Text box help?

I am making a site using fireworks and dreamweaver…but im a total newby with dreamweaver…

I made the site in fireworks - sliced it - and imported it into dreamweaver

there is a section I have for text, there is a background i want to keep.

I have put that slice in as a background - but now my problem is how do i add a text field on top that can scroll

so that i can put like 3000 characters in that section?

i been testing things trying to find the answer…i put a text field in there and set the character and the lines but i cant change the bg of that box or the font…

hope this makes sense…and i really hope someone can help
