From: Awrex on 5 May 2010 19:43 I'm trying to understand how/why this works... =OFFSET(A12,MATCH(MAX(E12:E300),E12:E300,0)-1,) So the reference cell is a12 - got that Understand the MATCH/MAX functions. I'm confused about the -1 aspect of the OFFSET function. If I understand this it's referencing one row below the reference A12... however it's referencing the same row.... the formula works, though I'm confused as to why... From: T. Valko on 5 May 2010 20:14 MATCH returns a number from 1 to n (or, possibly an error). So, if you want to include the value of cell A12 in the calculation then you have to correct the MATCH offset from 1 to n to 0 to n. To do that you subtract 1 from the result of MATCH. Let's assume E12 is the max value of the range. So: MATCH(MAX(E12:E300),E12:E300,0) = 1 If you didn't use the -1 correction then you'd have: =OFFSET(A12,1,) = A13 With the -1 correction you have: =OFFSET(A12,0,) = A12 Another way to do this is with the INDEX function: =INDEX(A12:A300,MATCH(MAX(E12:E300),E12:E300,0)) -- Biff Microsoft Excel MVP "Awrex" wrote in message news:FDDE1903-0669-4BB1-9CF0-28BF75AD8408(a)microsoft.com...> I'm trying to understand how/why this works... > > =OFFSET(A12,MATCH(MAX(E12:E300),E12:E300,0)-1,) > > So the reference cell is a12 - got that > Understand the MATCH/MAX functions. > I'm confused about the -1 aspect of the OFFSET function. > If I understand this it's referencing one row below the reference A12... > however it's referencing the same row.... the formula works, though I'm > confused as to why...  |  Pages: 1 Prev: Present Value of equal payments of a future valueNext: IF AND question
