>>I think the trigger fires with INSERT INTO but you have to be careful what you are inserting. If you are setting something like a unique primary key the INSERT INTO will err because INSERT INTO has already violated the uniqueness of the field, if, it is not specified in the VALUES list or a memvar. INSERT INTO puts a null value anywhere VALUES is not specified for a field. This why I continue to generate index keys with a global routine .vs a stored procedure.

Is the ID unique or is it set to not accept null values?
