<p>How do you generate a X.509 public and private key pair and a signing request (CSR file) to be sent to a CA for signing in C#?</p>

CountIf can count values equal to one chosen. Unfortunately it seems that there is no good candidate for such function. Alternatively you can use additional column with If to display 1 or 0 if the value fits in range or not accordingly:
```
```
=If(AND({list_cell}>=MinVal; {list_cell}<=MaxVal); 1; 0)
```
```
Then only thing left is to sum up this additional column.
