Auto fill a subform based on a common field

Auto fill a subform based on a common field

In my current database I have all of our customer information and the order information in one table.  Every time a customer reorders we create a new record with all of the customer info and the new order info.  In my trial with Creator I see that you have a "subform" option which seems like a much better way to handle the information.  I split the information and imported it in two different Forms, one for the customers and one for the orders.  In the main "Customer" form I added a subform so that I can view all of the orders for that customer.  What I want to do is populate the subform based on the address for the customer which is the same as the address for the order.  I have tried the lookup fields to no avail, and there is way to much information to retype everything,  Any ideas on how to populate the subform?

example: Customer A lives at 123 Main street.  There are 5 different orders that have been delivered to 123 Main Street.  How do I get those 5 orders to show up in the subform for Customer A?
