I have a doctor’s database and part of it is a patient close out form. On the form I want to have a field that shows the patient’s opening balance. I created a query that calculates by patient the sum of the procedure charges and the sum of the patient payments, and an expression field that gives me the balance the patient owes. What I’m trying to do is pass the value in the OPEN_BAL field in the qryPAT_SUM query. I’d tried to use the control source property for the text box on the form, but I’m doing something wrong. If anyone has any ideas or if there’s a better way to handle this, and can help I would really appreciate the help. Thanks Tom
