>>Just to check the basics, what's the field type of your field, and do you have a record for IsoChanges in ID.dbf? What number is luID when it returns, and does that change on repeated attempts?

>The field is of type integer in the IsoChanges table, in Id.dbf I have the "IsoChanges" record with the correct value and IncrementProcedure. The luId changes on repeated attempts. But I got it to work, but for only a view based on the table. In MM, you can use the dbf directly and it will update... but for some reason I cannot use the dbf, but I can use a view based on the dbf...

I've only ever used views with MM, not tables directly. Wish I had something more to offer.
