Has Anyone Had Trouble Updating A Record Before?

Hi, I have a problem, it is that when I try to update a record in my SQL server database, it is not updated and I recieve no error messages. This is the code behind the update button. The stored procedure is "sqlupdate".











Code Snippet

Dim ListingID As String = Request.QueryString("id").ToString
Dim con As New SqlConnection(ListingConnection)
Dim cmd As New SqlCommand("sqlupdate", con)
cmd.CommandType = CommandType.StoredProcedure
Dim id As SqlParameter = cmd.Parameters.Add("@id", SqlDbType.UniqueIdentifier)
id.Direction = ParameterDirection.Input
id.Value = ListingID

Dim PlaceName As SqlParameter = cmd.Parameters.Add("@PlaceName", SqlDbType.VarChar)
PlaceName.Direction = ParameterDirection.Input
PlaceName.Value = PlaceNameTB.Text

Dim Location As SqlParameter = cmd.Parameters.Add("@Location", SqlDbType.VarChar)
Location.Direction = ParameterDirection.Input
Location.Value = LocationTB.Text

Dim PropertyType As SqlParameter = cmd.Parameters.Add("@PropertyType", SqlDbType.VarChar)
PropertyType.Direction = ParameterDirection.Input
PropertyType.Value = PropertyTypeTB.Text

Dim Description As SqlParameter = cmd.Parameters.Add("@Description", SqlDbType.VarChar)
Description.Direction = ParameterDirection.Input
Description.Value = DescriptionTB.Text

Try
con.Open()
cmd.ExecuteNonQuery()
con.Close()
Catch ex As Exception

End Try
