I need to be able to set set a deadline based on prior dates. These can go
back years. I would like to set up a current 'next appointment, for instance
ever 90 days, based on a date of arrival. For example, if date of arrival is
2/13/03, how do I make a formula that is effective now. In other words, the
cell updates to a new deadline every ninety days, and stays current.
Thanks a bunch.
