Help Needed to create a formula to add values assigned cumulative dates in a month

I have a variable list of items in date order, there could be one, more than one, or, no items for any one date
Each item has it's own line
I need a formula in a separate column (column F) to total each day's items ...

Column A includes the Date
Column F is a cumulative total (as in Column C) for items on the same date

Column C=D+E

I am looking for a formula which will add up items in column C if they have the same date in column A, and put the answer in the last cell in column F for that date. Any ideas?

Example
A B C D E F

Try this formula in F2:

=IF(A3=A2,"",SUMIF(A$2:A2,A2,C$2:C2))

copied down.

Check out the SUMIF function in Excel Help...

The $ sign "freezes" the row number...so that we are always summing from the top when column A has the same date that is in column A of the row the formula is in...
