I have a basic sheet that refreshes external data based on what someone
fills in for starting and ending dates in a couple of cells. The data is
just a bunch of customer order lines that have the customer id, part, qty,
price, etc.

I want a variety of summaries of some of the data on the side of the sheeet
or where ever, but I don't know the functions to use that will do somethnig
like the following automatically.:

Date --- Avg $ --- # of Ord --- Total$ --- Total Units
1/1/08 -- $15.00 -- 20 --- $500 ---- 300
1/2/08 -- $10.50 -- 10 --- $500 ---- 100
1/3/08 -- $12.35 -- 12 --- $500 ---- 250
