count visible merged cells in Excel 2010

Question

I have Excel sheet as below with merged cells in column A

in Cell D1 SUBTOTAL works fine

But when i filter Column b as below

SUBTOTAL not count MERGED cells, it only count row 22.

I tried use Countif but it count all rows(visible and hidden)

How i can count all visible rows on column A?

Answer 1

I would use the following workaround: in cell C2 use formula =INT(SUBTOTAL(3, B2:B4)>0) and similar formulas in cells C5, C9, C13, C16, C19, C22.. just replace B2:B4 with the respective range of rows of the merged cells. The formula will tell you whether at least one of the rows in a group is visible. Then make SUM of all values in the column C.
