UPDATE [hisc sc -2] SET [hisc sc -2].SuperChain = [hisc sc -2]![Chain]
WHERE ((([hisc sc -2].SuperChain) Is Null));
This is from a different Query where I am trying to update empty "superchain" fields to what is in the Chain field. It has worked in the past, but now it doesn't.
Also my Make tables queries worked today, but did not yesterday.
