Jan,
You have a couple of issues here. First of all, double-quotes on strings
are no longer valid in IB 6 or Firebird. Double-quotes now have a specific
syntactic use and strings MUST be single-quoted. Either of these
double-quoted strings could be the source of your "invalid column
reference", since Firebird expects anything in double-quotes to be a
metadata object.

Second, you almost certainly need to use the AS keyword in IBO4 and
provide a name for the output column, when outputting a computed column, as
you do here.
