Your question is ambiguous, and certainly not depicted as
an Excel formulas, (note spelling of Excel)

B9: =SUM(B$4:OFFSET(B9,-1,0))
the difference is that you can insert rows without having to
change your formula. Read more about at http://www.mvps.org/dmcritchie/excel/offset.htm http://www.mvps.org/dmcritchie/excel/insrtrow.htm
