I have a pretty complicated sheet that is calculating the average for the last 3 days, 6, 12 and 24 days. I have noticed that the answers fro 3 & 6 days are correct, but the 12 & 24 days are not correct.

[FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]=AVERAGE(OFFSET(C1,0,COUNT(C2:ZY2)-3,16,3)) is correct answer!
[/FONT][FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]=AVERAGE(OFFSET(C1,0,COUNT(C2:ZY2)-6,16,6))
is correct answer!

These are not correct
[/FONT]<strike></strike>
=AVERAGE(OFFSET(C1,0,COUNT(C2:ZY2)-12,16,12))
<strike></strike>
=AVERAGE(OFFSET(C1,0,COUNT(C2:ZY2)-24,16,24))


the formula only counts cells with numbers in them. I have checked and there are no zeros, the formatting is for numbers. I am stumped as to why this is happening. Any help would be appreciated

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.
Hi
Welcome to the board

Excel won't care about formats when performing the calculations.

Confirm that you have only number values.

When the formula

=AVERAGE(OFFSET(C1,0,COUNT(C2:ZY2)-12,16,12))

does not work ok, use in another cell:

=COUNT(AVERAGE(OFFSET(C1,0,COUNT(C2:ZY2)-12,16,12)))

and check that it's 192.
