I am working on building a calculated field using 3 date columns on a list and I am having difficulties due to being 3 dates and If/Else. Basically it should calculate a date based on if date1 is not null add 90 days, else (if date 1 is null) use date 2 plus 90 days, else (if date 2 is null) use date3 plus 90 days.
This is what I have so far. I may be completely wrong. Any help is appreciated.
