Can't understand why two values are different

[leopardhawk]

Hello forum friends, I am testing a workbook to make sure there are no errors and I am having problems figuring out why these two values are different when they should be exactly the same. If anyone has any ideas as to why, I will be very grateful.

There are two columns on one worksheet (income), one with dates that are two weeks apart and the other with dollar amounts (see below). This formula returns $947.03.

=AVERAGE(H12:H33)

The other worksheet (personal_info) has a date of birth for the user (see below).

This formula returns $990.08, a difference of $43.05! This is what I can't figure out, if the user is under 65 years of age, the formula should be returning the same amount, no?

=IFERROR(AVERAGEIFS(income!H12:H500,income!F12:F500,"<"&EDATE(personal_info!E9,(65*12))),0)

With that data both formulae return $990.08

When I copied your data, this formula:

=AVERAGE(H12:H33)

returned $990.08 for me (as did the other formula).

Are you sure that you have place that formula on the correct page?

Check to see what these formulas return:
=COUNTIF(F12:F33,">0")
=COUNTIF(H12:H33,">0")

They should both return 22. If they do not, they you probably have one or more entries entered as Text and not Numeric.

maybe:

=IFERROR(ROUND(AVERAGEIFS(H12:H50,F12:F50,"<"&EDATE(E9,(65*12))),2),0)

complete the formula with the names of the worksheets

Many thanks to Fluff, Joe & Sandy! I found that I had an extra row on my worksheet that was blank and therefore messing up the data! Thanks to all for your assistance!

Cheers!
