Don't worry about the autonumber field, just keep adding your records. When you go back and review, you will find the autonumber field properly filled in.

Question
How to generate autonumber value on add new record
Hi Guys,
Hoping you can help me out. I have a form to enter a new record in a table. The primary key of the table is a long integer autonumber field. I set the form to DataEntry "yes" to it opens blank. Which means it does not populate that autonumber field with the next value. I added a command button at the bottom to add the record. However, whenever clicked, I get an error because obviously the autonumber field is still null and is required and not allowed to be null. I have tried many of the solutions I have found here, but no dice. Any idea how I can put the next increment of that autonumber field in there before it attempts to add the new record to the DB? Thanks.

Thanks for the quick input all. I guess I will try to explain a little more. The problem is that when I click to add, it tells me that field is null which isn't allowed. When I set the form to be DataEntry, it no longer auto populates that key autonumber field with the next value. It is left blank. Which is why I am trying to generate it. I did try the DMax in the beforeInsert but it kicked back a type mismatch.
Me.txtID.Value = DMax("id", "users") + 1
txtID is the form textbox, id is the db field and users is the database table
Hi
Please upload the db if you can....Autonumber will always be populate automatically and you cannot change the value. Try to do add some data in data entry and close the form, go to table and see if primary key number was generated if you cannot add the record in the form go to the table and add the data and try to go to next row you should get the same message.
As mentioned above check table design and check all fields which have required property set to yes also check validation rule (is not null). Also if you haven't build the form check if any of the controls on the form are not set up to required = yes.
Uploading portion of the db should be the quickiest way to help you.

Emil

You really can't do that. The AN is not created until the 'new record' becomes 'Dirty' ... which happens as soon as any 'bound' control becomes edited in some way (character in a text box, etc.).
Further, you cannot *reliably* get the AN until the record has been saved.
