auto id is not shoing up in all tables

[jriley]

I have created several tables that share an auto id number, I have created the relationships exactly the same in every table, but for some reason the auto is (primary key) only shows in the first two related tables and not the others. When I go to enter data in the other related tables it gives an error saying my primary key field is null and when I open the table sure enough the auto id is not there. Any suggestions what might be causing this? I've never had this happen before.
Thanks!

There is nothing in Access to automatically place a PK in a table just because you have defined a relationship. What did you do to get the first two tables to work?

I have always just allowed access to create the autoid (which I did in this case)and that id was in each related table. I am using the auto id as the PK in this case.

The only object in Access that works in the background to insert Keys is the SubForm. If each table you have has an AutoNumber as a PrimaryKey, then each time you add a record to those tables it will create another PK for you. It will not however make it the same PK as another table. Your first post indicates to me that your other tables do not have the PK set as an AutoNumber.

Update, I did a repair and compact again, and this seemed fix the issue. I'd had already done this, but I gave it shot and did it again and it seems to have worked. I have absolutely no idea why. thanks!

I'm still not sure of your configuration but glad you got it working.
