Thank you for another excellent tutorial!  I am very much looking forward to the upcoming videos.

When using the record selector, ContactF worked perfect for me.  I was a bit concerned at 7:35 where you selected Barbara from the dropdown and CustomerID 10 appeared on the form with ContactID 33 and its related note.  I saw this again at 13:55 when you selected Anna Picore CustomerID 5 who then appears with ContactID 32 which was previously assigned to CustomerID 8.

It made sense to me after you stated that the Contact Form will be a subform.  Am I right to assume that ContactF will be a data-entry form where ContactID will be populated only after the selection of the customer?
