how do you scroll text up in a text box?

Hi,
I think I must be missing something obvious because I see this done everywhere but haven't figured out how to do it yet.
I have 1 rich text box control that is large and is set for vertical scroll.
I have a text box control that is just one line in height. I want to type into the text box and then have whatever I type show up on the rich text box. I can get the text there easy enough, but it starts at the top and works it's way down.
I'd like to have all of the incoming text start at the bottom and have the older text be displayed above it....just like on any chat type program...so how do you do this?

Thanks

It sounds like your appending your list box text to the top (or front) of the rich textbox test ie.

richbox.text = newtext.text & richbox.text

Just swap the 2 boxes like:

richbox.text = richboxtext & newtext.text

That will put the new text at the bottom of the rich textbox. You may have to scroll the rich textbox to make the new text visible.

...scary.
