    Countif with 2 columns 1 criteria and no duplication

    Hi everyone,
    I spent a lot of time trying to find the correct formula I needed but didn't find anything.

    I want a formula to find how many countries has RED as colour while excluding repetition of countries. So the formula needs to count the number of countries in the column "country" that has RED in the column "colour" all while excluding the repetitions in column "country"

    For example below it would be 3 countries : Mexico (twice but I want it counted as 1) India and China

    Can anyone help ?
    Thank you
    J.


    Country---Colour

    Mexico---Red
    Benin---Orange
    Canada---Blue
    Mexico---Green
    India ---Red
    Mexico---Red
    China---Red

    Try this:

    =SUMPRODUCT((1/(COUNTIF($C$4:$C$11,$C$4:$C$11))*($D$4:$D$11="Red")))

    where the C range contains countries and the D range contains colours.

    Hi, thank you for your quick feedback. I tried it but excel tells me that there is an error in the formula. I tried to replace the , with ; it gives a totally wrong number

    There are 17 Red and 11 countries (if I count each country only once) but it gives me 9.333333

    Re: Countif with 2 columns 1 criteria and no duplication

    Hello J2424 and Welcome to Excel Forum.
    This proposal employs a helper column (C) based on the word Country being in cell A1 and the first instance of Mexico being in cell A3.
    The formula for C3 is: =AND(COUNTIFS(A$3:A3,A3)=1,B3="red")
    After pasting the formula into cell C3 drag the fill handle down to cell C9.
    Note that the helper column could be moved and/or hidden for aesthetic purposes.
    The formula to count distinct entries is: =COUNTIFS(C3:C9,TRUE)
    Let us know if you have any questions.
