Hi! I'm trying to see if a nested Hash key exists. If it does, I want to delete it. Here's what I've written.

if (exists %{$rHoH_ProteinFamilies->{$proteinfamily}->{$PROTEIN}})
{
delete $rHoH_ProteinFamilies->{$proteinfamily}->{$PROTEIN};
}

Here's the error.

exists argument is not a HASH or ARRAY element or a subroutine at HoH.pl line 123.

Thanks in advance!
