I have a form setup. custom. Very simple. I simply added a few basic text box form fields where I wanted them.

What I am trying to do is reference text box(1) into text box(2) and change the font to 3of9 barcode in text box (2).

This way the user types the text into text box(1), can read it, and when I get the form it also has the barcode below it in another text box that I can use.

How can I do this?

And how do I make the REF field automatically update from the original when the user types data into the linked text box?
