Using Access 2003

I have one table called customers and a table called orders. The primary Key
is CustomerID and the foriegn key is attached to Orders. I then created and
orders and customer forms. I want it so that when I have a Customer name on
the first form I only want orders from that customer to show up on the orders
form. I have tried creating a 1 to many relationship. That did not work for I
deleted. I did a insert a subdatasheet but it only saved that first
cumstomer's information. Please help? Jennifer
