Sub forms and Tab control primary key help

[Cris]

I am a school student working on a Microsoft accessdatabase, and have little experience in the software.
I have created an input form for students to enter theirinformation using sub forms and tab controls. I have 5 separate tables thatrecord specific data: student details, contact details etc. From these I maderelated forms. In my combined student input from, each tab in the tab control hasa sub form from these individual table forms. After inputting all of my data, Iopened the related tables and realised that the primary key used by all thesetables/forms was only being recorded from the first tab (student details). Inthe other tables/forms (contact details etc.) a primary key for that record isgiven from that table's ID, but not the relating foreign key.
When I created the sub forms I linked them through thewizard with this primary key, however, it does not record in my tables. When Icreated the blank from my initial record source was the Student Details tables,however I’m not sure if this has something to do with the problem. Is there a method to either fix or work around this issue?

Do you really need 5 tables?

Why are student details and contact details in separate tables? Student has multiple contacts (addresses, phones, emails)?

If you want to provide db for analysis, follow instructions at bottom of my post.

I guess I have many tables in order to improve clarity, also note that some of these tables are for processing orders. The tables for the forma are: Student details, Contact Details, Medical Details, Order Details, and travel details. Even if I merged the

Student details, Contact Details, Medical Details and Travel Details tables. I still need separate tables for the orders and products. I believe my problem is in the linking of the primary key with the subforms. Do you have a solution?

Without more info on data relationships, first impression is need a main form bound to StudentDetails then subforms bound to each of the dependent tables. Set Master/Child Links properties so the StudentID will save as foreign key to each of the dependent tables.

What I did was link the main form to the Student Details tables, then create the other subforms, linking via the studentID.
