As I understand it now, the principle in this case is;
Bind the controlsource to the key of the parent tabel in the child table
(orders.cust_id) and bind the rowsource to a field in the parent table (customers.name)

Although I don't use a grid this is basically what i've done.
This way my combobox reflects the name of the customer currently connected to the particular order.

I've experimented with your suggestion with regard to boundTo = .t. and boundcollumn = 2, but without the desired results.

As my case is a very simple one, customer table has only two fields: cust_id and name, and just three records. I might not need to set the other two properties.

When I change a customer the orders.cust_id value is replaced with the correct value, this might be coincidental.

Anyway Thanks.
