    Highlight positive and negative numbers based on data from another column

    Abc 500
    abc -500
    bbb 300
    bbb 250
    cac 100
    cac -100
    ddd 200
    ddd 300
    fff -500

    I want to be able to highlight data in column B where amount is identical (ignore negative sign) only where data in column A is identical.

    In this particular case it should highlight 500,-500 where data in column A = ABC & also 100,-100 where data in column A =CAC.

    Hi,

    Assuming your data is in A1:B9, enter the following in C1

    =SUMPRODUCT(($A$1:$A$9=A1)*($B$1:$B$9=-B1))

    and copy down to C9

    A result of 1 indicates a match.

    Rule 2: See rule 1

    id go for
    =SUMPRODUCT(($A$1:$A$9=$A1)*(ABS($B$1:$B$9)=ABS($B1)))>1
    which you can use as a formula rule in conditional formatting
