[Don''''t have a clue :(]

Hello.
I have created a word Document with a tables and with in thoses tables there
are "Text Form Fields".

What i would like to do is that if i input a value in to "text form field"
box #1 I would like that info to be also written to a position in the header
part of the document.

Also the document will be locked

Does anyone have any ideas, Thanking you
