As promised, here's a sample ASP report from Northwind using my ASP Report Class (http://weblogs.sqlteam.com/jeffs/posts/526.aspx). 

Hopefully, everyone will agree that the script is very easy to write and read and much shorter.   All grouping (for both headers and footers), subtotals and running totals are completely taken care of by using the class, and it is giving you recordset functionality (movenext and EOF and column reference by name) using the speedy GetRows() method under the hood.

For this to work, you must have the class saved as “ReportClass.asp“ in the same folder as this script (notice the include).

' here we declare our Report object and intialize it

set g = new Report

g.Init r,array("SalesPerson","CustomerID","OrderDate"), array("Quantity","Discount","ExtendedPrice")
