Stored Proc Date Range Nor Producing RS

I am going crazy. I have a typical date field in tbl_Feedback(smallDateTime) that is storing just the date portion. I have a stored proc that I want to dynamically retrieve records within a certain date range (typical!). I am using ASP/ADO, etc. When I run the following Stored Proc in SQL Analyzer, it works (if I replace the variable "@sDate" with '10/01/2004' --There ARE records within this date range.) Further more, If I run a simple Query on the Feedback table and do the same, it produces results, but when I call the stored Proc from the web page, I get 0 results when attempting to PASS date values dynamically. I tried to pass them as actual date types, still 0. I'm now attempting to pass it as a 10 length string ("10/01/2004") and converting it to a date, still 0. What am I MISSING???

-- Procedure

CREATE PROCEDURE sp_009_SiteLead
@sDatenVarChar(10)

AS

--DECLARE @CurDate datetime
DECLARE @StartMonth int
DECLARE @StartYear int
DECLARE @StartDay int
DECLARE @StartDate varchar(10)


SET @StartMonth = DATEPART( month, Convert ( datetime, @sDate ))
SET @StartYear = DATEPART( year, Convert ( datetime, @sDate ))
SET @StartDay = DATEPART( day, Convert ( datetime, @sDate ))
SET @startDate = CONVERT( varchar(2), @StartMonth ) + "/" + CONVERT( varchar(2), @StartDay ) + "/" + CONVERT( varchar(4), @StartYear )
Print @startDate

SELECT *
FROMtbl_Feedback
WHERE tbl_Feedback.DateIn >= @startDate
GO

--- ADO Web page

' Stored Procedure Name: sp_009_SiteLead
' Site Lead Default Query

set cmd=server.CreateObject("ADODB.command")
set psDate = cmd.CreateParameter("sDate", adDBTimeStamp, adParamInput)
set cmd.ActiveConnection=DBConnection
cmd.CommandText="sp_009_SiteLead"
cmd.Parameters.Append peDate
cmd.Parameters.Append psdate
psDate.Value = "10/01/2004"
Set rsObj = CreateObject("ADODB.Recordset")
rsObj.ActiveConnection = DBConnection
rsObj.CursorLocation = adUseClient
rsObj.PageSize= 20
rsObj.Open cmd

Again, If I replace the @startDate variable in the stored proc with a date surrounded in single quotes, I get the expected results, but it just does not understand my date if I pass it.
Can anyone help?

Thanks,
