Richard uses a combo box in the appointments form to get customer names from customers table so the right customer is displayed in the form. It uses customer ID in combo box to get customer and hides the ID column. But what if two or more customers share same first and last name - how do you know you have the right customer. You dont want to put appointment details that pertain to wrong customer. Would displaying additional fields in combo box like address information help to narrow down and icrease accuracy of customer search in the combo box. Also - maybe cos i am new how do you add a new appointments details to this form not just see the customers historical appointment details.
