Form Field Auto sum dates

[Jazdog]

I'm trying to create a document (letter) wherein Form field (Date) would
automatically update based on the manual entering of information, i.e., if I
typed in a date in one section of the letter, the date in another section
would auto calculte to 60 days later.

Dateplus45ateAdd("d",45,[Date])
This takes your [Date] field, specifies days, 45 days, add 45 days to [Date].
DateAdd("w",1,[Date]) would add one week.
See this link for more information about dates.
