Grab primary key and use it in subform

Hello,



I am building a user creation form.

i set it up like the screen shot in the first attachement. 3 different tabs.

In tab 1 you create the user which then gets a unique key (DocentenID).

Table 2 you can input more information about the user (in a different table)

i want it to grab the primary key (DocentenID) and insert that into a field in the other table same goes for tab 3.

Has anybody got a idea how i can realise this.



thanks in advance.
