excel - MAX date value within a range with 2 conditions -


to make easy

+---+----+-------------+ |   |  |      b      | +---+----+-------------+ | 1 | xx | 12-05-2015  | | 2 | xx | 15-05-2015  | | 3 | yy | 13-05-2015  | | 4 | yy | 16-05-2015  | +---+----+-------------+

(today 14-05-2015)

i need max date value each "a" value if before today. in case it's not, move 2nd biggest value. case not find, empty cell.

what i've done far:

=max($a$1:$a$4='xx';$b$1:$b$4<today();$b$1:$b$4)

and confirm shift+ctrl+enter

the error yields 13-05-2015 max value xx, wrong (as if not take account $a$1:$a$4='xx'

you need use nested if-functions. i.e. change formula into:

{=max(if($a$1:$a$4="xx", if($b$1:$b$4<today(), $b$1:$b$4)))}

and end ctrl+shift+enter
