How to create a new record and automatically assign id from another table

[estergr]

The DB that you supplied has 324 LineaT records, with no OPN NomeLinea records. Have you tried the DB in post#13? The searched for NomeLinea does not need to be near the first. In fact, if it's the 9000th record in LineatT, it will be automatically SHOWN and SELECTED if you type its name in the combobox.

Yes I tried. The db I gave to you was with few lines just to make you understand. In the picture I underlined the OPN cells. if I type OPN in the search combobox I have no results.

Ah, OK. You need wildcard searches. Try DB ver3. In your example, type OPN and hit ENTER. Type into Scatola, ENTER for more filtering, as with Gruppo. The available selections in each combobox restrict the valid selections in itself and in the others.
The values in the dropdowns are guides, showing valid searchable values.

That's it. Brilliant. Thanks very much. I'll see tomorrow at work, with all the records how it goes.

Thanks again
