In cell B16 I want to count how many "B"s (the value in A16) are in cells C1:C15 and A16. Then using some function I will put an "A" or "B" in cell C16. How can I give such a range in COUNTIF? The same formula must be used for every cell in column B.

Answer 1

Here's the formula for cell B16: =SUM(COUNTIF(INDIRECT({"C1:C15","A16"}),"B"))
