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.

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.

Why am I still getting 0? And not the value of 3?

Text maybe, what happens if you test the values with =ISNUMBER(A1)
=ISNUMBER(B1)
then copy down as long as needed to cover the values in A and B
if you get any false then you have text and I showed how you could correct
that unless you want to sum the values as opposed to count them

Yes I need to sum the values in column B

So did you test if they were text using those formulas (you can also use
=ISTEXT(A1))
