1. Add both of your tables to the report. Link from the CustID in tblVisitDate to the CustID in tblCustomers.
2. In the Select Expert, set up your selection criteria.
3. In the report, group on the Customer name + the CustID (so that you get one for each different customer, even if two or more have the same name!)
4. Suppress the detail section. Put your mailing label data in one or more Group Header sections. This way you'll only get it once, even if the customer had more than one visit that meets the selection criteria.
