expression.Item(var)
expression Required. An expression that returns one of the objects in the Applies To list.
var Required Variant. An expression that specifies the position of a member of the collection referred to by the expression argument. If a numeric expression, the var argument must be a number from 1 to the value of the collection's Count property. If a string expression, the var argument must be the name of a member of the collection.
Remarks
If the value provided for the var argument doesn't match any existing member of the collection, an error occurs.
The Item method is the default member of the References collection, so you don't have to specify it explicitly. For example, the following two lines of code are equivalent:
Debug.Print References(1).Name
Debug.Print References.Item(1).Name
