Collection item not found

You tried to refer to a nonexistent member of a collection. For example, assuming a collection class IntegerCollection:

Dim varV As Variant
Dim IntCol As New IntegerCollection("astring",10)
Print IntCol(3)		' Illegal because the collection doesn't have any
					' members.

Add members to the collection before trying to refer to them; specify an index that identifies a member; or remove the reference.
