Help with count of missed Critical Parameter

[Azerate]

Hi Folks,

I need some help to display the number of missed Critical Parameter formula.
I decided to change the (0,1,NA) value for (n,y,NA) as it was causing an issue on the database pivot.
But i get an error when changing the formula....

As you can see on the screenshot below, when i add a 0, on the bottom you can see count of critical parameter is at 1,

i would like to be able to change the whole formula to count n,y instead, is it possible ?

Some help please/ideas ?
