string, the COUNTA function counts that value. The COUNTA function does not count empty cells. 
• If you do not need to count logical values, text, or error values (in other words, if you want to count only cells that contain numbers), use the COUNT function. 
• If you want to count only cells that meet certain criteria, use the COUNTIF function or the COUNTIFS function.
