Farahbakhsh,

>1. How do I force the contents of one field to contain one or more other fields?

It is not a good idea to store calculations in a field because that introduces the possibility of data inconsistency (when the fields in teh calculation are equal to the calculated field. Instead, do the calculation when you need it.

You can get your result into a field using the REPLACE command;

REPLACE Field3 WITH Field1 * Field2

>2. Every time I try to add security in VFE, I get errors suggesting that the tables and views created by VFE (i.e. appgroups, appusers, etc.) cannot be found and are in fact never created. Do I have to create them my self or am I forgetting something?

I would post this question in the section for VFE.

>3. I would like to make my application work so that when I enter in an id number, it automatically searches the database for that id number, and once found, it enters information from the database into already created read-only text fields. How do I go about doing this?

This is not a simple question that lends itself to a forum message. You need to look at the textbox class. IN the textbox for searching you would probably use the InterActiveChange evetn to look up the textbox value in your table and then do Thisform.Refresh()

You should put textboxes for all of the fields you want displayed and set their ControlSource to the field that should be displayed.
