    sequential numbering duplicate data

    I have a worksheet (brief copy attached) that has duplicate data "h" that I want to assign a sequential number to the left column of. 1st "h" 1, 2nd "h" 2 and so on to be used for a vlookup function in another sheet.This sheet is constantly growing with an copy/insert macro I created so I need it to expand as other entries "h" are made. Here is a before and after example.

    Re: sequential numbering duplicate data

    Do you mean something like:

    =IF(B3="h",COUNTIF(B$3:B3,"h"),"")

    copied down as far as you want so that when you add more, the formula is already in column A.
    Where there is a will there are many ways.
