I am trying to "COUNT" the number of a certain object in column I (in this instance) across multiple sheets. That value in column I is the result of a formula (if it matters). So far I have:
=COUNTIF('Page M904'!I:I,A13)+COUNTIF('Page M905'!I:I,A13)+COUNTIF('Page M906'!I:I,A13)
which works, but I am going to have 20 something pages to scan through. I would like to avoid having a page long formula.
I have tried
=COUNTIFS('Page M904:Page M906'!I:I,A13) and
=COUNTIF('Page M904:Page M906'!I:I,A13)
but that results in a #VALUE.
And I think
=COUNTIFS('Page M904'!I:I,A14,'Page M905'!I:I,A14,'Page M906'!I:I,A14)
is a misapplication of the COUNTIFS because I get 0 when it should be 35.
I am trying to avoid using VBA for this application. But if has to be, then it has to be :) Thanks in advance for your time and help.

'Page M904:Page M906'!I:I- good attempt, but unfortunatellyCountifdoesn't support 3-D references..I am trying to avoid using VBA. But if has to be, then it has to be:)- you could write quite simple user defined function for this.=COUNTIFS('Page M904'!I:I,A14,'Page M905'!I:I,A14,'Page M906'!I:I,A14)returns 0 because in that phrasing it becomesIF...AND, rather thanIF...ORas you want it.'Page M904'!I:IbecomesM904i. But still, there are 20+ of this naming.
