Hi Matt,
There is quite a lot involved to synch forms. First of all, you need your tables to be set up with the proper relationships. Once you do that, try Access help and type in "Synchronize" and click on "Forms". There is everything you need to know there and several examples you can explore. I have pasted a topic below. Hope this points you in the right direction.
Best regards,
Henr¥
From Access Help: Example of using Visual Basic to display related records when you move between records
When you move between supplier records on a Suppliers form, you may want to see the products each supplier carries in a Products form. In the Form_Current event procedure of the Suppliers form, set the FilterOn and Filter properties of the Products form:
Private Sub Form_Current()
' Declare and set a variable to store the WHERE
' clause that describes the records you want to
' display.
Dim strCond As String
strCond = "SupplierID = Forms!Suppliers!SupplierID"
' Use the IsLoaded function from the Northwind
' sample database to check whether the Products
' form is open, then set the properties.
If IsLoaded("Products"

Then
Forms![Products].FilterOn = True
Forms![Products].Filter = strCond
End If
End Sub
