I have a spreadsheet that I need to add a column subtotal for column C and
column D. the number of rows will vary from one run to the next. the other
issue I have is that all rows with a value in column D are listed (by sort)
below all rows with a value in column C. I can add subtotals, but I do not
know how to set the range to be dynamic. Also, I need the subtotals to be 2
rows below the last row with a value in column D. I am stumped!
