Scrolling Panel Containing Dynamic Text

Hi,

Is it possible at add text contained within a variable to a scrolling text panel.

I am currently using a text box containing "%variable name%" and dropping this text box onto the scrolling panel.

The result is that the text appears (at a reduced font size) but there is no scroll bar.

Any help, or clarification that this is not possible, would be appriciated.

Thanks,

Matt
