I dont know how to use storedProcedure that returns one value as a result to a VB calling

My stored procedure works perfectly when I run Query Analyser, but when I run my VB program I get the eror: I get the message : An SqlParameter with ParameterName'@.total' is not contained by this SqlParameterCollection.

Here is my stored Proc and my VB program is right below

I- Stored Proc:

CREATE PROCEDURE dbo.totalsub
@.account bigint,
@.total bigint output
AS
select total=sum(SubPhnNmbr) from tblsub whereSubAccNmbr=@.account
return
GO

II- And my pogram in VB is:

Dim totsub As Int64
Dim cm As New SqlCommand
Dim cn As New MyConnection
cn.open
'my connection is defined by me don't worry about it
cm.CommandType = CommandType.StoredProcedure
cm.CommandText = "totalsub"
cm.Connection = cn
Dim pm As SqlParameter
pm = cm.Parameters.Add(New System.Data.SqlClient.SqlParameter("@.Account", System.Data.SqlDbType.BigInt))
pm.Value = 100000165
pm = cm.Parameters.Add(New System.Data.SqlClient.SqlParameter("total", System.Data.SqlDbType.BigInt, 4))
pm.Direction = ParameterDirection.Output
totsub = cm.Parameters("total").Value
cm.ExecuteScalar()
totsub = cm.Parameters("total").Value

I also tried using @.total instead of total and I tried ParameterDirection.ReturmValue instead of ParameterDirection.Output

No Luck, someone pls can help

I don't know How can i upload my sqlserver file to the server
could you help me?
could you write an example code in query analyser for
uploading sql server file to databaseDo you have access to the SQL Server on the server? That is, can you connect to the server from the machine with your SQL Server? If so, you can use DTS (in internet explorer, right click on the database and select Import (or export, depending upon the database you right click on).
