In my form, there is two combox.
One is Cust_id and the other is Cust_Name.

The Table Customer has those two index.
So, when click CobCust_id, Set the order to Cust_id and search
whereas Click CobCust_Name, Set the order to Cust_Name and search

Problem: after one search and refresh, click other combox will give a Wrong Reference number.

Cust_id:   [L606]
Cust_Name: [Mary Ltd.] 

When click [Mary Ltd.], will see:

Cust_id:   [L606]
Cust_Name: [Mary Ltd.] 
           +Caroline Pacific+
           +Cas...          +
           ......

Which is not starting at [Mary Ltd.]

Similiar, when fix the Cust_name, the click on CUst_id change quite far from expected!
Why?? I have code:

SELECT CUSTOMER
curCust_Name = Cust_Name
SET ORDER TO Cust_Name
LOCATE FOR Cust_Name = curCust_Name  && to ensure fit to the selected one!!
