This is a sumproduct formula I have worked out to count the number of
recordable events that occurred within a date range.

=SUMPRODUCT((Data!A$2:A$2550=ListValues!A2)*(Data !A$2:A$2550<ListValues!B2)*(Data!H$2:H$2550="Recor dable"))

Now what I am trying to do is capture the cost of these recordable events
(adding another array to sumproduct). These costs are located in cells
Data!K$2:K$2550.

I have not been able to get this $ total by using sumproduct. Somehow I
keep screwing up. The only way I have been able to get this total is by
using conditional sum- but by doing this I am not able to "pull" these
calculations to adjacent cells- and I'm summarizing 20 years of data, so with
each calculation only giving me a month-total, I could be entering the next 3
days if I don't figure this out.

So here's the conditional-sum formula that gives the total- but that I have
to enter each time:

=SUM(IF(Data!$A$2:$A$2500=ListValues!A2,IF(Data!$ H$2:$H$2500=A19,IF(Data!$A$2:$A$2500<ListValues!B2 ,Data!$K$2:$K$2500,0),0),0))

Is it possible to get to this total with SumProduct?
