Object is invalid or no longer set. (Error 3420)

You are attempting to reference an object that is no longer valid or has not been set.

Possible causes:

• The object has been closed.
  
  
• The object has been orphaned (the parent object has been closed or deleted).
  
  
• The object is out of scope.
  
  
• The object library is not registered in the Windows Registry.
  
  
• You are trying to reference a method or property of the collection, but you have not assigned it to a variable first. For example, to reference the Name property, use the following:

  Dim dbsPublish As Database
  Set dbsPublish = OpenDatabase("BIBLIO.mdb")
  dbname = dbsPublish.Name
