I'm a bit lost here. Surely, the field used in your main table to show 
the Member's ID in your main form should reference the Member ID of your 
e-mail table, via a FOREIGN KEY relationship between your tables ? 
Perhaps I have misunderstood what exactly it is that you are trying to 
achieve or how exactly you have structured your tables ?

If you need a value to appear in your main table, which is taken  from 
your email table, then use the FOREIGN KEY relationship definition. If, 
however, you are inserting a value of MemberID into your e-mail table 
from your main table, then you need to have the MemberID field of your 
email table defined as a FOREIGN KEY reference for the main table. You 
can't expect both tables to know simultaneously whether to refer/receive 
at the same time, that won't happen as you would have created a circular 
reference.

Your questions seem to me to be far more related to how to normalize 
your data relationships than how to get Base to do what you want with 
them, and would probably be better asked in a forum dealing with such 
questions, but I could be misreading / misunderstanding the whole point.
