[real estate, not doc prep!]

I'm very new to this, and pretty much teaching myself how to use mail merge
while trying to develop forms for my company...

SO - very simple: I'm putting together Request for Proposal letters where I
have to fill in the current date, proposal due date, draft date and final
report date.

How do I create fiels for each date so that the document essentially "asks"
the user what date to fill in each field?

Thanks!
