Heres kinda how my spreadsheet looks:

Code:
--------------------

A B C D
1. Disc Cost Adj Result
2. Sample1 $1.00 -1 -$1.00
3. Sample2 $5.00 -5 -$25.00
4. Sample3 $1.00 -1 -$1.00
5.
6. Sample1 $1.00 -1 -$1.00
7. Sample1 $1.00 -1 -$1.00
8.

--------------------


What I need is all the cells in row "D" to multiply C*B (easy), but if
there is nothing in C, then I need it to sum up the values in D (from 1
above it to the next break in numbers). So D5 would = -$27.00, and D8
would = -$2.00. This is what I have come up with so far (D5):


Code:
--------------------
=IF(C5="",IF(C4="","", ???),C5*B5)
--------------------


Any ideas?
