    Compare data across 7 columns for duplicates

    Hello,

    I have a spreadsheet with 8 columns of data. I am trying to figure out how automatically tally how many times each entry in the last column (H) exists in the previous 7 columns (A - G). Each entry in column H could only exist 1 time max in each of the other columns but doesn't have to exist in any columns.

    Any ideas?

    Roger

    Try this in I2

    =COUNTIF($A2:$G2,$H2)

    Drag/Fill Down

    Hope this helps

    Close. Only I need it to search and tally ALL of column A-H, not just cells in the same row.

    Aye....burp! .... beer yum-yum

    A worksheet showing your non-sensitive data and the result expected would be an advantage!

    Wouldn't it just be:

    =COUNTIF($A:$G,$H2)
