Try the below. With your data as below try the below formula in cell D2.
Please note that this is an array formula. An array formula can perform
multiple calculations and then return either a single result or multiple
results. Array formulas act on two or more sets of values known as array
arguments. Each array argument must have the same number of rows and columns.
You create array formulas in the same way that you create other formulas,
except you press CTRL+SHIFT+ENTER to enter the formula. If successful in
'Formula Bar' you can notice the curly braces at both ends like "{=<formula}"

=INDEX(B1:B9,MAX(IF(A1:A9=C2,IF(B1:B90,ROW(B1:B9) ))))

Col A Col B Col C Col D
Date Value Query date Result
9/8/2009 0 9/8/2009 =formula
9/8/2009 3

with the formula I have =0

31/09/08 100
31/10/209 0
30/11/08 0
31/12/08 84.06
31/01/09 0
28/02/09 0
31/03/09 78.77
30/04/09 0
31/05/09 0
30/06/09 79.17
31/07/09 0
31/08/09 0


and I want to have as a result 30/6/09 or 79.17
to calculate the value for the 31/8/09 I need to know the previous value

formula help
 

Now I use this formula =INDEX(B3:B600;MATCH(9.99999999999999E+307;B3:B600 ))
and works

column B:B I have my values but I also need the date in column A

How can I get the date corresponding the value I get in the formula?

thanks

Try the below (array formula Use CTRL+SHIFT+ENTER to enter the formula)

=INDEX(B1:B100,MAX(IF(B1:B1000,ROW(B1:B100))))

The earlier formula retrives the last value for the date mentioned in cell C2

To return date
=INDEX(A1:A100,MAX(IF(B1:B1000,ROW(B1:B100))))

To return value
=INDEX(B1:B100,MAX(IF(B1:B1000,ROW(B1:B100))))

Note that both are array formulas
