I need to use SUMIF to calculate a subtotal of column B based on the criteria
of column A. The problem is, the column A has names of group in every 10th
cell or so, and column B has many repeated numbers which could vary month to
month.

Example)
Col A Col B
group A a
b
c

group B a
b
c
d

I need subtotals for group A & B, even when group A has "d" listed in Col. B
in other months.
Please help. Thanks.
