Excel 2002. I have a sheet containing 27K rows of data, each row
referenced by a reference number in column A. Many of the rows have
duplicate or triplicate references e.g.
01/010/0002
01/010/0014
01/012/0020
01/012/0020
01/012/0020
01/013/0134
01/014/0004
01/014/0004
but contain different values in subsequent columns.
What I need to do is identify the rows where the references are the same
and sum data in the corresponding rows e.g. for 01/012/0020 above I need
to sum the contents of column C for the 3 related rows and for
01/014/0004 sum the contents of column C for the 2 related rows. I know
how to identify duplicates in column A using =countif(A:A,A1) which will
give me 2 where there is a duplicate entry or 3 where there is a
triplicate entry, but I am not sure where to go from there. I imagine
that I need to extract the data to another range to sum the data in
column C for each reference.
Grateful for any assistance.
