Word 2003 - Forms

I am adding form fields that can be tabbed through by entering TextFormFields
into my document. The form is to be used as a template for a three part
perferated form. Question #1: Is it possible to set some Fields to populate
automatically based on the information entered in another form field? In
other words, if my document has two name fields, I want to type the name in
one field and it automatically be entered in the other name field. Question
#2: Is it possible to set the form field that is automatically populated so
that it does not allow a user to enter anything manually? In which case, I
would not want the document to allow a cursor to enter that field during a
tab stop.
