List.Add not set to an instance of an object

[KGCole]

Hi, I've got a method where I'm trying to add an object to a list, and Visual Studio debug gives me an error that what I'm trying to add is "not set to an instance of an object". I set my list to be List(Of Object), and also set my variable to a FileSystemWatcher object, but still get the error. Breakpoint just tells me the same thing. Here's my code...if someone has any ideas why I'm getting this error I'm open to suggestions. I've also tried setting everything to string type, but still get the same debug message. Here's my code:

Public FSWList As List(Of Object)

Public Sub SetupFileWatcher(fswPath As String, fswPlan As String, fswFilter As String, SyncObject As Form)

            Dim fsw As FileSystemWatcher = New FileSystemWatcher(fswPath)

            If fswPath.Length = 0 Then
                Return
            End If

            fsw.BeginInit()
            fsw.SynchronizingObject = SyncObject
            fsw.InternalBufferSize = 32768
            fsw.IncludeSubdirectories = True
            fsw.Filter = fswFilter
            fsw.Path = fswPath
            fsw.NotifyFilter = NotifyFilters.FileName Or NotifyFilters.CreationTime

            AddHandler Me.Created, New FileSystemEventHandler(AddressOf Me.OnCreated)
            AddHandler Me.Deleted, New FileSystemEventHandler(AddressOf Me.OnDeleted)

            fsw.EnableRaisingEvents = True
            fsw.EndInit()

'this is the line that is giving me the error
            FSWList.Add(fsw)

        End Sub

Thanks for any ideas.
