Find last occurrence of specific value in a row

Question

I have a table that keeps scores from fantasy football league. The lowest scoring week is not included in the total.

I\'m able to find the lowest score using the

Answer 1

You will need to use an Array Formula to achieve this. The following will return the "highest" lowest value if you are using columns B:R as the data columns and column T as the Low Week column. You need to enter this as an array (CSE) formula by copying and pasting it into cell T2 and pressing Ctrl+Shift+Enter.

=IFERROR(INDEX($A$1:$R$1,1,SMALL(IF(B2:R2=MIN(B2:R2),COLUMN(B2:R2),FALSE),COUNTIF(B2:R2,MIN(B2:R2)))),"")

Explanation

First, the COUNTIF(B2:R2,MIN(B2:R2)) will count the number of times the minimum value occurs. This is needed because a simpleMIN(B2:R2) will only grab the first minimum value, not the nth minimum value.

Next, the IF(B2:R2=MIN(B2:R2),COLUMN(B2:R2),FALSE) is the actual array formula part of the equation (the reason why you need to use Ctrl+Shift+Enter). It will only return the references for when you have a minimum and returning FALSE for all other entries greater than the minimum. Now, you have an array of only the column numbers the smallest values in the dataset.

Then, the SMALL(IF(B2:R2=MIN(B2:R2),COLUMN(B2:R2),FALSE),COUNTIF(B2:R2,MIN(B2:R2))) will take the column numbers of the smallest values and find the latest occurrence of this, which comes from the COUNTIF(B2:R2,MIN(B2:R2)) code.

Now that the last smallest occurrences' column number is know, you can use the INDEX function to find the value in the first row INDEX($A$1:$R$1,1.

Finally, the IFERROR will display the Low Week row if the SMALL function finds a match, otherwise it will display a blank cell. This could be used to copy this array formula further down the page for rows that you don't yet have users for.
