I am trying to write a formula that works off what is in two separate cells.
It has several parts and maybe not all of them can be done. It would be
great if someone could help me out. Here goes.
If A2 & A3 each have a "N" in it then I want cell A5 to show today's date
plus 20 weeks. However, if only 1 of the cells A2 or A3 has a "N" in I still
want A5 to show today's date plus 20 weeks.

Can this also be done? If both A2 & A3 have "Y" in them then I want A5 to
freeze with the date last show when 1 of the two cells had a "N" it it.
