user input of a startDate and an endDate in aspRunner 6.

I have a simple SQL query which works fine in aspRunner
SELECT LocationID, poCust, SKU, SUM(qty) as QTY

from zPo

GROUP BY LocationID, poCust, SKU

ORDER BY LocationID, poCust, SKU
based on this table
CREATE TABLE [dbo].[nameOfTable](

[LocationID] [int] NOT NULL,

[poReceiptID] [int] NOT NULL,

[poDate] [smalldatetime] NOT NULL,

[poCust] varchar NOT NULL,

[SKU] varchar NOT NULL,

[Qty] [numeric](10, 2) NOT NULL

) ON [PRIMARY]
Now the user want to be able to query within a date range, say between 2011-05-01 and 2011-05-15.
In SQL I could write it like this:
DECLARE @DateFrom date, @DateTo date

set @dateFrom = '2011-05-01'

set @dateTo = '2011-05-15'

SELECT LocationID, poCust, SKU, SUM(qty) as QTY

from nameOfTable

WHERE podate >= @dateFrom and podate <= @dateTo

GROUP BY LocationID, poCust, SKU

ORDER BY LocationID, poCust, SKU
Any suggestions how to make aspRunner to "prompt" the user to input dateFrom and dateTo so it is used in the query above - preferbly in the Advanced Search Page.
A thanks in advance from my users who will really be grateful for your help.
