Use COUNTIF and ISNUMBER

cantpickname

I want to count the number of cells that do not contain a number. I have this easily calculated in a report using the filter of "is not a number" but I would like to replicate within a sheet writing a formula.

The field is the Amount, I am getting the #INCORRECT ARGUMENT SET error message. I feel like this is something simple I am missing.

=COUNTIF({Amount}, NOT(ISNUMBER({Amount})))

L_123

=COUNTIF({Amount}, NOT(ISNUMBER(@cell)))

L_123

=COUNTIF({Amount}, NOT(ISNUMBER(@cell)))

cantpickname

Knew it was something easy, thank you @L@123
