I have a table, tblindividual, which holds names and addresses of officers.
The primary key is ID. Each year they have to complete a registration form
and return it to us in order that we can then send out a new registration
card. So I have a table tblIDCards with Primary key CardID, and these fields
ID, txtidform (date field) and txtidcardissued (also a date field) I have
two problems to keep an annual record.
1. I have a form called frmMain (this is a menu form) with a subform,
frmRegistration, which is based on a query which includes tblIndividual and
on this form is a tabcontrol called  TabCtl44. On one of the tabs I have
another sub form frmidcards based on tblIDCards which is linked to the
frmRegistration by the primary key ID from tblIndividual and the field ID
from tblIDCards (the foreign key???). I have a control on frmRegistration
called IName (a calculated control whose control source is =[txtfirstname] &
" " & [txtsurname]) and I have a control on the subform frmidcards called
IName2 whose control source should reference IName with this as the control
source.
=Forms!frmMain!Subform1!frmRegistration!IName.
The subform frmidcards is in datasheet format so that we can enter the
relevant dates each year and view the history.
However I get the dreaded #Name? so my control source must be incorrect. Can
anyone tell me where I've gone wrong with that problem.

2. When I try to enter data in the subform frmidcards I get an error message
that says
The LinkMasterFields property setting has produced this error: 'The object
doesn't contain the Automation object 'tblindividual."
What does this mean?

Hope I've explained my problems. Any help would be appreciated.
