how do i find the last specific value in a column?
i have 2 columns of data. the first is a box number from 115 the second is
the time and date the part was weighed. i want to find the last time a box number was used, say 9, and have the corresponding date copied to another cell. thank you in advance for your help, BS. 8 4/25/2006 15:15 11 4/25/2006 15:16 9 4/25/2006 15:16 10 4/25/2006 15:17 15 4/25/2006 15:18 2 4/26/2006 7:15 9 4/26/2006 7:15 7 4/26/2006 7:16 5 4/26/2006 7:24 9 4/26/2006 7:24 14 4/26/2006 7:24 15 4/26/2006 7:26

how do i find the last specific value in a column?
To find the last 9 in A1:A100:
Ctrl/shift/enter: =MAX(ROW(1:100)*(A1:A100=9)) Then use this value (say it's in E1) as input to the Index: =INDEX(B:B,E1) HTH Bob Umlas Excel MVP "bradsmith37" wrote in message ... i have 2 columns of data. the first is a box number from 115 the second is the time and date the part was weighed. i want to find the last time a box number was used, say 9, and have the corresponding date copied to another cell. thank you in advance for your help, BS. 8 4/25/2006 15:15 11 4/25/2006 15:16 9 4/25/2006 15:16 10 4/25/2006 15:17 15 4/25/2006 15:18 2 4/26/2006 7:15 9 4/26/2006 7:15 7 4/26/2006 7:16 5 4/26/2006 7:24 9 4/26/2006 7:24 14 4/26/2006 7:24 15 4/26/2006 7:26

how do i find the last specific value in a column?
This turned out to be the perfect solution for this query can you please
elobarate the formula. As per the syntax it shoud be: LOOKUP(lookup_value,lookup_vector,result_vector) result vector that is B2:B13 (Date & Time) is understandable lookup_value = 2 ??Why so Lookup_vector = 1/(A2:A13=9)?? confused.

how do i find the last specific value in a column?
Let's use this example to demonstrate how this works:
...........A.............B 1.....header.....header 2........9.............10 3........7.............12 4........9.............15 5........5.............16 Return the value in column B that corresponds to the *last instance* of 9 in column A. =LOOKUP(2,1/(A2:A5=9),B2:B5) This expression will return an array of either TRUE or FALSE: (A2:A5=9) A2 = 9 = 9 = TRUE A3 = 7 = 9 = FALSE A4 = 9 = 9 = TRUE A5 = 5 = 9 = FALSE We then use the divison operation to coerce those logical values to numbers: A2 = 1 / TRUE = 1 A3 = 1 / FALSE = #DIV/0! A4 = 1 / TRUE = 1 A5 = 1 / FALSE = #DIV/0! At this point the formula looks like this: =LOOKUP(2,{1;#DIV/0!;1;#DIV/0!),B2:B5) The way that LOOKUP works is if the lookup_value is greater than all the values in the lookup_vector it will match the *last* value in the lookup_vector that is less than the lookup_value. The *last* value in the lookup_vector that is less than the lookup_value is the second 1. The #DIV/0! errors are ignored. We use a lookup_value of 2 because we know that the result of this expression: 1/(A2:A5=9) will not return a value greater than 1. This is how that would look: ...........A.............B 1.....header.....header 2........1.............10 3...#DIV/0!.......12 4........1.............15 5...#DIV/0!.......16 So, the *last instance* of 9 was in A4. Return the corresponding value from B4. =LOOKUP(2,1/(A2:A5=9),B2:B5) = 15 Biff "Shweta Srivastava77" wrote in message ...
