Flash/XML gallery: make desc_txt box different size?

Hi, I just did the tutorial for the flash/xml photo gallery. I understand everything pretty well, but I want to make the desc_txt box accept larger text amounts and a smaller/different font. I changed the size of the box and made the font smaller, and it doesn’t show up in the final product. I looked at the action script, and I don’t see anything to do with the text info. I’m using Flash 8, but also have access to CS3, so I might try it on there later this week. Thanks for any help.
