I use the following formula: =COUNTIF(D5:P5,"x")

In this case, I am counting the number of "x" between D5 and P5. You can
change the "x" to "K" if you want and identify the range you want to count,
up and down a column or as I have done in a row.

The "double unary minus" converts a logical (TRUE or FALSE) value to a
number (1 or 0).

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