index is not a valid index in the Collection object. |
|
The Collection object is read-only. -or- The Collection object has a fixed size. |

Remarks
If index equals the number of items in the Collection object, then value is appended to the end.
In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hash table.
