I have a sheet that has text in column A, a amounts in column B and dates in column C. In row 1, columns O through Z I have the names of Months (January..December).
In the January column, row 2 (cell O2), I want to create a formula that will SUM all values in column B where MONTH(C#) = 1. Likewise in cell P2, I want to sum all rows in column B where MONTH(C#) = 2. And so on.
The result is 12 formulas, one for each month, that displays the total amount in colukmn B for that month (or 0 if nothing exists yet for the month).
