You can get the totals for each customer into a separate cursor like so:

SELECT inname, SUM( bill_total ) AS customer_total FROM csrBillTotals ;
  GROUP BY inname ;
  ORDER BY inname INTO CURSOR csrCustomer_totals

You can relate the 2 cursors like this:

SELECT csrCustomer_totals
INDEX ON inname TAG inname
SELECT csrBillTotals 
SET RELATION TO inname INTO csrCustomer_totals
