SUMIF with only one criteria cell within range

[Guest]

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.

Hi
it would be much easier if you could fill column A completely with the group
name. Could you change this layout?

Hi
if you like email me a sample file and I'll create some formulas for this

Maybe I'm missing something, but can I have your email address?

There are some quick techniques for filling blank cells here:

Or, add a column, and calculate the group there.
For example, in cell C1, enter: =IF(A2<>"",A2,C1)
Copy the formula down to the last row of data.
Use the new column in your subtotal formula.
