Unless I am missing something – this is a classic case of using Pivot Table.
I used your data in Excel 2007 & got this type of result.
Row Labels A B Grand Total
2007 2 3 5
2008 1 2 3
2009 3 1 4
Grand Total 6 6 12
Is this what you have in mind? You may just read up on Pivot Table. By the way, Pivot table handles large files. I noticed that the columns did not line up properly when I copied & pasted Excel data. There are 4 columns - Year, A, B, and Grand Total
