Thank you very much for helping.
But can you tell me, what does the two minus before (--ISNUMBER... do?

Hi.
I want to count all cells in a range that contains the letter K.

The example here would return 3 because 3 cells are containing a name

has K in it.
I think I should put functions like SUMPRODUCT AND ISNUMBER AND MATCH,
