which is an array formula, so commit with Ctrl-Shift-Enter

I am currently working on the following document excerpt

Worklist Received Reported Days to Report
AUT 5/16/2005 6/7/2005 22
AUT 6/28/2005 6/28/05
BM 1/3/2005 1/4/2005 1
BM 1/3/2005 1/6/2005 3

I am trying to find out the number of "worklist" items per month
(Received)
and then divide the number of "Days to Report" by that number to get
the
average days per item. The following calculation I have is not
working on
"numeric values"

my

formula:=SUMPRODUCT(--(IndexData!$G$5:$G$23330=1/1/2005),--(IndexData!$G$5:
$G$23330<=1/31/2005),--(IndexData!$A$5:$A$23330="BM"))
