    How to compare and highlight a column based other columns matching without replacement?

    So I have a table...

    A B C D E F G
    54 8:45 Jane Paul 8:45 37
    37 1:12 Dave Chris 5:35 78
    78 5:35 Chris Jane 6:40 90
    90 6:40 Jane Liz 2:05 14
    37 8:45 Paul Sarah 7:30 54
    82 3:14 Matt Jane 8:45 54
    14 2:05 Liz Dave 1:12 37
    54 7:30 Sarah Mike 9:00 14
    14 9:00 Mike Matt 3:14 82


    Basically, what I need to happen is high light the values in Column A if they match those in Column G if the data in the corresponding columns (B and C) match those in F and E.

    I understand this may not be entirely clear.

    I need it to identify that for each row, columns A B and C match 1 row in columns E F and G.

    For example, it would see that B1 = "8:45" and C1 = "Jane". Then it would look for a row where E= "Jane" and F = "8:45". These would be E6 and F6. Once these two rows are determined, it would see what the corresponding values from columns A and G are. So A1="54" and G6="54". Therefore, both 54's would be highlighted.

    It should be noted that there are instances in which there could be multiple "Jane"'s or "8:45"'s or "54"'s in the columns. This is demonstrated in the table above. So the matching would need to be one-to-one or "without replacement". So once a row a cell or group of cells is used for a match, it is no longer used for future comparisons. This is incredibly important to the project because there will often be duplicates; some intentional and some by mistake.

    If any of this is still unclear, please let me know. I find myself struggling with the appropriate wording of the problem.

    If this can be done in conditional formatting as opposed to Macros, that would be ideal.

    Thank you very much.

    will this work for you?

    EDIT: formula updated - changed from SEARCH to MATCH.

    - i.s.z -
    CSE, aka Array aka { }, formulae are confirmed with CONTROL+SHIFT+ENTER.
    Replace commas ( , ) with semicolons ( ; ) in formulae, if your locale setting demands.
    All good ideas are courtesy resources from this forum as well as others around the web.
