[dba-VB] Zoom Box

Hi all, I'm creating a "Zoom" box for text fields.  Ie, when the user
double clicks a form text box, a form with one text field appears and
the contents of the text box are fully displayed without having to
scroll through it.  The easy part is opening the box and populating. 
How do I get the contents from the zoom box back into the form text
field that it was called from?  I've tried saving to string or form but
I'm not having any luck.

Thanks for your help.
