Using a variable as the end of a SUM range?

[Guest]

I need to set up the sum of a row whereas the end of the range varies. Example:

In January, I need to add from January to January; in February, from January to February; and so on. I'd use something like =SUM(A1:CurentMonth). Anybody?

Aloha,

The way I did mine was to link cells in the worksheets. I ahve 12 sheets named for the months. In the Jan sheet, I have a target cell for the sum of Jan. In Feb, I also have a target cell for the sum of Feb + the sum of Jan. In Mar, I have a target cell for Mar + Feb. The formula would look something like for FEB.
=sum(b1:b30)+(jan!a31)...etc
