I just learned something new. I have two tables populated by a script. Up until today I never had occasion to use the second. Both tables have a field set to validate as unique (they shouldn't be). The first of the two fields set to unique has "Allow user to override . . .". When the script populates the first table it overrides the validation automatically. The second one fails. I had always thought overriding validation had to be done manually. Not so.
