Answer 1

Ok I think I understand your problem. Are you usign SQL Server 2005 or newer?

If so, you can do this with the "OVER" clause, wich will let you do sums and get all the other columns. here's a way to do this

SELECT sum(billsItems_Quantity) OVER (PARTITION BY /*group by columns for the sum here*/) as TotalQ , 
   sum (billsItems_ItemDiscount) OVER (PARTITION BY /*group by columns for the sum here*/) as TotalD , 
   sum (billsItems_ItemTotal) OVER (PARTITION BY /*group by columns for the sum here*/) as TotalI , 
   bills.bills_ID , billsitems.billsItems_BillItemSerial , bills.bills_CashierID , 
   bills.bills_StoreID , billsitems.billsItems_Unit , billsitems.billsItems_Price FROM bills , 
   billsitems 
WHERE bills.bills_ID = billsitems.billsItems_BillItemSerial
  and bills.bills_CashierID = '".$id."'
  and bills.bills_StoreID = '$ausers_StoreId'
order by billsitems.billsItems_Unit 

Answer 2

I guess it is because you did not add GROUP BY, try

    SELECT sum(billsItems_Quantity) as TotalQ , 
        sum(billsItems_ItemDiscount) as TotalD , 
        sum(billsItems_ItemTotal) as TotalI , 
        bills.bills_ID , 
        billsitems.billsItems_BillItemSerial , 
        bills.bills_CashierID , 
        bills.bills_StoreID , 
        billsitems.billsItems_Unit , 
        billsitems.billsItems_Price 
    FROM bills , billsitems 
    WHERE bills.bills_ID = billsitems.billsItems_BillItemSerial
      and bills.bills_CashierID = '".$id."'
      and bills.bills_StoreID = '$ausers_StoreId'

    GROUP BY bills.bills_ID , 
        billsitems.billsItems_BillItemSerial , 
        bills.bills_CashierID , 
        bills.bills_StoreID , 
        billsitems.billsItems_Unit , 
        billsitems.billsItems_Price

    ORDER BY billsitems.billsItems_Unit

You have not provided a lot of details, but you might be able to use a subquery for the sum() and then join back to your table:

SELECT i1.TotalQ , 
    i1.TotalD , 
    i1.TotalI , 
    b.bills_ID , 
    i2.billsItems_BillItemSerial , 
    b.bills_CashierID , 
    b.bills_StoreID , 
    i2.billsItems_Unit , 
    i2.billsItems_Price 
FROM bills b
INNER JOIN
(
    select sum(billsItems_Quantity) TotalQ,
        sum(billsItems_ItemDiscount) as TotalD,
        sum(billsItems_ItemTotal) as TotalI,
        billsItems_BillItemSerial
    from  billsitems
    group by billsItems_BillItemSerial
)  i1
    ON b.bills_ID = i1.billsItems_BillItemSerial
inner join billsitems i2
    on b.bills_ID = i2.billsItems_BillItemSerial
WHERE b.bills_CashierID = '".$id."'
  and b.bills_StoreID = '$ausers_StoreId'
order by i2.billsItems_Unit
