In Visual Foxpro 9 I am trying to wite an sql with a product "subtotal" column and a report "total" column. The sql code that works is as follows, but when I insert the commented out "Case" code I get errors that seem to increase as I correct the preceeding error. Can any one tell me in which place I should insert the "case" and what is wrong with the code?
SELECT qItemSaleLines.ItemID, ; qItems.ItemID, ; qItemSaleLines.SaleID, ; qSales.SaleID, ; qSales.CardRecordID, ; qCustomers.CardRecordID, ; qItems.ItemNumber AS ProdCODE, ; qItems.ItemName AS StkNAME, ; qCustomers.LastName AS CUSTOMER, ; qSales.InvoiceNumber AS SaleINVNo, ; qSales.InvoiceDate AS SaleDATE, ; qItemSaleLines.Quantity AS SaleQTY, ; qItemSaleLines.TaxExclusiveTotal AS SALE, ; qItemSaleLines.CostOfGoodsSoldAmount AS COGS, ; qItemSaleLines.TaxExclusiveTotal - qItemSaleLines.CostOfGoodsSoldAmount AS MARGIN, ; (qItemSaleLines.TaxExclusiveTotal - qItemSaleLines.CostOfGoodsSoldAmount) * / qItemSaleLines.TaxExclusiveTotal AS MPERCENT ; FROM qItemSaleLines, qItems, qSales, qCustomers ; WHERE qSales.CardRecordID = qCustomers.CardRecordID AND qItemSaleLines.SaleID = qSales.SaleID AND ; qItemSaleLines.ItemID = qItems.ItemID AND qSales.InvoiceDate > {^2009-06-30} ; ORDER BY qItems.ItemNumber, qSales.InvoiceDate ;

*!* (SELECT qItems.ItemID, qItemSaleLines.ItemID, qItemSaleLines.TaxExclusiveTotal, ; 
*!*         CASE WHEN qItems.ItemID = (SELECT TOP 1 qItems.ItemID FROM   qItems.ItemID, ;
*!*             WHERE qItems.ItemID = qItemSaleLines.ItemID, ;
*!*             ORDER BY qItems.ItemID desc), ;
*!*         THEN (SELECT SUM(qItemSaleLines.TaxExclusiveTotal) FROM qItemSaleLines.TaxExclusiveTotal,; 
*!*             WHERE qItems.ItemID <= qItemSaleLines.ItemID AND qItems.ItemID = qItemSaleLines.ItemID, ; 
*!*         ELSE ' ' END AS 'PROD-SALE'), ;
*!*     CASE WHEN qItems.ItemID = (SELECT TOP 1 qItems.ItemID FROM qItems.ItemID, ; 
*!*             ORDER BY qItems.ItemID desc), ;
*!*     THEN (SELECT SUM(qItemSaleLines.TaxExclusiveTotal) FROM qItemSaleLines.TaxExclusiveTotal, ;
