Hi,

I'm comparing monthly data for the current year 2005 with monthly data for
2004 - easy-peasy for the month-on-month variance!

My sheet has data for all 12 months of 2004, but I'm only filling in 2005
data as it becomes available. However, I want to show an accumulated total
variance to date - i.e. the 7 month totals (jan-Jul2005) v. the corresponding
7 months totals for Jan-jul2004. How can I create a summing formula that
adjusts accordingly?

Many thanks,

Enzo
