Thread: Conditional Formatting w/ errors

I was wondering it were possible to reference an error.
I'd like a cell to have white text if $O19 produces a #N/A error.
I tried formula

=($O19=#N/A)

and the formula

=($O19="#N/A")

but neither work.
Any help would be much appreciated.

Hi,

Code:

=ISNA(O19)
