Excel funtions

I am trying to perform a "=Daverage" over a large data
base that includes over 100 counties and over 2500
townships. Each county has from 20 to 80 townships in it
with a specific value attached to each township. I need
an average of these values in each county. I can do it by
using the "=DAVAERAGE" fuction, but I need to manually
change the criteria for each and every county to get that
county's average and I cannot figure out how to do all
counties easily. I can easily do this in Lotus123 by
doing county #1 then copying it to the remainder of the
counties, but it does not work in Exel. Can anyone give
me some help. I have Window 98 and what ever EXCEL
version that came with it.
