Interactive Text

(did I word the title correctly?)
Hi Kirupa Flash Script Forum -
I apologize if I missed this tutorial somewhere, but I am trying to add interactivity, or style rather, to text. For example, I’d like my users to be able to type in a text field and then choose from a selection of colors and fonts and whatever they type in the field instantly changes to their chosen color and chosen font without refreshing the page each time. Is that an extremely hard script? and/or is this an existing tutorial on Kirupa?
Thank you!
