Hi Elizabeth

One way, in A2 enter
=IF(C2=C3,"",SUMPRODUCT(($C$2:$C$100=C2)*$B$2:$B$1 00))
and copy down.

Change ranges to suit the amount of your data, but note that Sumproduct
cannot take whole column ranges (apart from XL2007)

I am trying to total the number of line items per ID# in a particular
column
within a spreadsheet, as pictured below. I do not want to create subtotal
rows, nor do I want to work with levels. I've tried various things with
the
IF, SUMIF and COUNTIF functions, to no avail. I am fairly new to all this
and would greatly appreciate any and all suggestions.

Thanks!


Number of Line Items per ID# Count ID#
