Your init is wrong. It should be:

Timer1.Initialize("Timer1", 2000)

Further explanation: When you initialize an object that takes an EventName parameter, you need to provide a "tag" for the events - but not the events themselves. The EventName parameter links the object's events to the object itself.

So for example, a Label has 2 events (Click & LongClick) - so obviously you can't initialize it with Label.Initialize("Label_Click") or Label.Initialize("Label_LongClick"), because then you would only be able to use one or the other event. When you initialize the Label, you use Label.Initialize("whatever"), then when you set up the event subs you will have:

Private Sub whatever_Click
...
End Sub

Private Sub whatever_LongClick
...
End Sub

So the value you provide in the initialization is the reference that B4A uses to make sure events are tied to the correct object.
