Totaling amounts based on duration

[ddbruno]

Hi,

I have three columns of data. What I am trying accomplish is totals
from one of the columns based on the difference between dates, i.e.
from the series of dates I would like to total the amounts where the
invoices were paid within a 7, 14, 21, etc. days. I tried using a
SUMIF statement using the dates as the range and ">=7" as the criteria
but continually get a zero value.

invoice_date date_apid amount
11/9/2005 12/7/2005 200.00
10/13/2005 11/9/2005 406.48
10/13/2005 11/9/2005 512.79
10/26/2005 12/7/2005 500.00
11/30/2005 12/14/2005 500.00
9/8/2005 10/26/2005 104.31
10/3/2005 10/26/2005 104.31
12/1/2005 12/28/2005 104.31
9/5/2005 10/26/2005 3,053.00
9/4/2005 10/26/2005 1,688.00
8/21/2005 9/28/2005 1,680.00
8/21/2005 9/28/2005 1,688.00
9/11/2005 10/26/2005 1,239.00
9/11/2005 10/26/2005 1,603.60
9/18/2005 10/26/2005 1,680.00
9/18/2005 10/26/2005 1,848.00
9/25/2005 10/26/2005 1,848.00
9/28/2005 10/26/2005 1,491.00
9/25/2005 10/19/2005 1,584.00
10/2/2005 10/26/2005 1,680.00
10/2/2005 10/26/2005 1,848.00
10/2/2005 10/26/2005 2,640.00
9/15/2005 12/7/2005 80.00

I appreciate any help.

Thanks

=SUMPRODUCT(--($B$2:$B$200-$A$2:$A$200<=7),C2:C200)

gives 7 days etc.
