please give structure of your three tables
Here is and example of what you may be looking
create a query
Code:
SELECT Customers.CustomerID, Orders.OrderID, Employees.EmployeeID, ([customers.customerID] & '' & [orderID] & '' & [employees.employeeid]) AS customerdetail
FROM Employees INNER JOIN (Customers INNER JOIN Orders ON Customers.CustomerID=Orders.CustomerID) ON Employees.EmployeeID=Orders.EmployeeID;
On your form base the three combo box based on your three fields
customerID - from Customer Table
OrderID - from order Table
EmployeeID - from Employee table
customerdetail= concatenation of all three fields (make sure this field exists in your table
when you create your combo box on customer make sure the source is like this
Code:
select distinct customerID from customers
and do the same for your other two fields
When you select each of the three drop downs, the customerdetail will be based on your selections.
I can work on another method but try this first
