    Solved: Sumproduct short question - count in sumproduct

    Hi all,
    i have one short question.
    How can i use function COUNT in SUMPRODUCT function?
    is it possible?
    i tried something like this:
    =SUMPRODUCT(--(Prer!$D$4:$D$2000=Prer!$D$3);--(Prer!$M$4:$M$2000<>"C");--(Prer!$R$4:$R$2000="R");COUNTA(Prer!$C$4:$C$1500))
    but it doesnt works
    Till now i use counting in sumproduct with column, where was only number 1 and it counted basics this column.
    It seems like this:
    =SUMPRODUCT(--(Prer!$D$4:$D$2000=Prer!$D$3);--(Prer!$M$4:$M$2000<>"C");--(Prer!$R$4:$R$2000="R");Prer!$Z$4:$Z$1500)
    where column Z was only for help with number 1.

    But this is not the right way in each case.

    how can i fix it?
    thx a lot

    COUNTA produces a single number, not an array. To multiply by this, take it out of the SUMPRODUCT
    =SUMPRODUCT(--(Prer!$D$4:$D$2000=Prer!$D$3);--(Prer!$M$4:$M$2000<>"C");--(Prer!$R$4:$R$2000="R"))*COUNTA(Prer!$C$4:$C$1500)

    I dont know why, but this return a very big number (2800 instead 9). Not the same as return if i use my old method with help column. Something can be wrong?
    I use sumpruduct and multiply it with counta (this count names in column).
