calling stored procedure from vba access gives run time error

[hfs]

I am trying to call a stored procedure from access ,but it is giving me this runtime error :

2147217900
Syntax error or access voilation

I am doing this first time so i dont know about how to pass parameters (IN and OUT)..

My code is

Public Sub createDataToAnalyze()


Dim objConnection As New ADODB.Connection

Dim objCom As ADODB.Command
Dim param1 As String
'Dim param2 As String

'Dim param3 As String

Dim provStr As String

Set objCom = New ADODB.Command

objConnection.Provider = "sqloledb"

provStr = "Data Source=BEA09;" & "Initial Catalog=Pending_ReviewsSQL;User ID=" & Environ("username") & ";Trusted_Connection=Yes;"
objConnection.Open provStr

With objCom

.ActiveConnection = objConnection
param1 = "300817"
.CommandText = "[ItemDesc]" & param1
.CommandType = adCmdStoredProc

Set param3 = objCom.CreateParameter("@desc1", adVarChar, adParamOutput, 220, adParamReturnValue)
objCom.Parameters.Append param3
Set param2 = objCom.CreateParameter("@desc2", adVarChar, adParamOutput, 220, adParamReturnValue)
objCom.Parameters.Append param2


Debug.Print (.CommandText)
Debug.Print (param3)
Debug.Print (param2)
objCom.Execute


End With
End Sub

when i print .CommandText it shows me
{ call [ItemDesc]300817(?, ?) }

My stored procedure is below :

USE [Pending_ReviewsSQL]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =================
ALTER PROCEDURE [ItemDesc]
	
	
	@ItemNo varchar(200) ,
	@desc1 varchar(220) out,
	@desc2 varchar(220)out
	
AS
BEGIN
	
	SET NOCOUNT ON;

    
select @desc1 = ProductDatabase.dbo.tblProductInfo.ProductDesc2,@desc2 = ProductDatabase.dbo.tblProductInfo.ProductDesc2 
from belqcdata01.ProductDatabase.dbo.tblproductinfo
where ProductDatabase.dbo.tblproductinfo.ProductNumber = @ItemNo




END

Need help with this...
Thanks

Your fifth argument of CreateParameter is invalid. You are trying to apply a ParameterType Enum to an Output Parameter. Leave it empty.

I have never seen a parameter passed ike this and I very much doubt it is valid.
.CommandText = "[ItemDesc]" & param1

Normally it would be added to the parameters collection.
