Getting A Concurrency Error?

The way I'm doing this is performing multiple reads on different tables to extract data. In this case I'm reading 2 different MS Access 2003 tables. I then dump the data into a "Row" variable that I have Publicly defined for each Class (each Access table is defined as a Class containing all the fields, Add, Change, Delete, and Select functions).For example, my first read extracts all the fields from the "tblClients" table and loads them into the form fields via the "clientROW" object. My second read extracts all the records from the "tblClientAddr" table associated with the selected Client and loads them into their form fields respectfully via the "addressROW" object.
