Wrong number of collection indices

You used more than a single subscript in referring to a member of a collection. For example, assuming a collection class IntegerCollection:

Dim IntCol As New IntegerCollection("astring",10)
'...
Dim varV As Variant
Set varV = IntCol
Print varV(1,1)		' Illegal.
Print varV(1)			' Legal.

Use one, and only one, subscript when referring to a collection member.
