Datasheet subform Link

(I have not done any Access in a while and have forgotten some simple stuff!)

Table tblCUstomers has one record for many records in tblMessages

Run StartForm which shows 2 sub forms.

What I Want:
Example: If I click on CustomerID=1 on the upper form then I want the lower form to display multiple records where tblMessages.CustomerID=1

My problem at the moment is that the lower form displays ALL records (which is incorrect).

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You miss to set the properties of the subform control:

LinkMasterFields: CustomerID  (or just ID, the key of tblCustomers)
LinkChildFields: CustomerID     (the foreign key for tblCustomers of tblMessages
