Thx for your reply,
it would have to be the first hit that lies within that 90 day period.
Also, it will have to pick the first of multiple one-date listings i
those happen to be flown on day 90.
Then, within those 'last 90 days' rows, it should SUMIF('type
flown';"B747400";"hours flown") so the end result is the totals fo
that type in the last 90 days.
Been trying over 20 combinations but I get error messages all th
time.
