Automaticly changing average function target cells
I am looking to create a function to only average the last 6 entries in a
list of numbers w/out changing the target cells of the AVERAGE function on a monthly bases. Example: I want to track scores on a monthly bases but only want the average of the last six months worth of scores. |

=AVERAGE(INDEX(1:1,,SUMPRODUCT(LARGE(COLUMN(1:1)*( 1:1<""),1))):INDEX(1:1,,SUMPRODUCT(LARGE(COLUMN(1 :1)*(1:1<""),6))))

This creates a #DIV Error.
Please explain this function so I may find the error Here is what I am Attempting to do.

Automaticly changing average function target cells
Bob's formula was configured to work along Row1, *across* columns.
Try this *array* formula, where the months are in Column A, and the values are in Column B. This is sized for 2 years, going from B2 down to B25: =AVERAGE(INDEX(B2:B25,LARGE(ROW(1:24)*(B2:B25<"") ,6)):B25) -- Array formulas must be entered with CSE, <Ctrl <Shift <Enter, instead of the regular <Enter, which will *automatically* enclose the formula in curly brackets, which *cannot* be done manually. Also, you must use CSE when revising the formula. -- HTH, RD --------------------------------------------------------------------------- Please keep all correspondence within the NewsGroup, so all may benefit ! --------------------------------------------------------------------------- "Phil H." wrote in message ...

Automaticly changing average function target cells
OK, Getting closer. The values in I4:I14 are as follows
1041.25, 1205.00, 1238.33, 1200.00, 1190.00, 1315.63 followed by 5 null cells. the array that I edited to be: =AVERAGE(INDEX(I4:I14,LARGE(ROW(4:14)*(I4:I14<"") ,6)):I14) returns a value of 1235.208333, though it should be 1198.368 when done manually using SUM(I4:I9)/6 The Columns next to this one do have values that might be being pulled, and also the cells I4:I14 do include funtions them selves. Though since I do not understand the Large or Row functions in this array I am having a hard time T/Sing the issue. Please Help.
