The value in column b does matter, so I should have said sum. Occasionally
the value is -1, which is where I started having problems.

Looking again at your original question, I see that I was reading it as sum
b1:b4, given the criteria in columns a and c, but that you actually said
"count b1:b4". Do the values in b1:b4 matter, or are you merely counting
the rows in which the a and c criteria are met? If you're only counting
rows and the column b values are irrelevant, omit the *(B1:B4) term in my
equation.

I'm trying to add the values in a column if the row includes two
different
criteria:

2800650 1 30200028
2800650 1 30200028
2800650 1 30200028
2800750 1 30200028


if the value in column a="2800650", and the value in colum c="30200028"
then
sum b1:b4
(in this case would = 3)
