I'm writing a COUNTIF formula referencing a column with multiple values that works well, until I try to build an expression that says:
I want you to count the values in this column as long as they are NOT "x" OR "y" OR "z".
Can anyone help with the proper syntax? I've tried the following but it doesn't work:
COUNTIF ({Reference}, OR(@cell<>"x", @cell<>"y", @cell<>"z"))
