cell c29 actually has no contents, but only contains formulas.
when cell c29 is calculated using COUNTA(c29) the result is 1, the result should be 0.
Does the COUNTA formula always produce 1 when the cell contains a formula?
The COUNTA function counts cellscontaining any type of information, including error values and empty text (""). For example, if the range contains a formula that returns an empty string, theCOUNTA function counts that value. TheCOUNTA function does not count empty cells.
