SQL Return Parameter

Hi Guys, I can't for the life of me get the output from the stored procedure into my variable in VB.net.   Can you guys help out, I'm on my third hour.  Trying to learn this peice as I go (output parameters).  I have truncated the code to look at the output parameter, everything works except the VB side of the output parameter, my messagebox keeps giving me a value of zero.  I have even tried  .SQLValue instead of .Value and it didn't work...thoughts????

Thanks in advance!

SQL:

ALTER PROCEDURE dbo.SDC_RisIncidentInsert
      @SeqInc int output
  
AS
Select @SeqInc = Max(Sequence) + 1 From _Smdba_._Telmaste_
Select @SeqInc

---------------------------------------------------------------------------------------------

VB.NetPrivate Sub InsertIncident()
Dim conn As SqlConnection
Dim comm As SqlCommand
Dim connectionstring As String = ConfigurationManager.ConnectionStrings("Magic").ConnectionString
conn = New SqlConnection(connectionstring)
comm = New SqlCommand("SDC_RisIncidentInsert", conn)
comm.CommandType = System.Data.CommandType.StoredProcedure

comm.Parameters.Add("@SeqInc", SqlDbType.Int)
comm.Parameters("@SeqInc").Direction = ParameterDirection.Output

Dim SeqIncident As Integer = comm.Parameters.Item("@SeqInc").Value
MsgBox(SeqIncident)

Try
  conn.Open()
  comm.ExecuteNonQuery()

Catch ex As Exception
  dberrorlabel.Text = "Could not Insert Incident Record"

Finally
  conn.Close()
  Response.Redirect("/RISDEV/SDC_Incident.aspx?Name=" & SeqIncident & "#Incident")
End Try
End Sub
