How to copy an object?

[LaVolpe]

Is your collection only going to contain single numbers? If so, use an array instead of a collection and you can copy that easily enough.

Regarding your error: h.Add a.Item(x)
or use a For Each loop, but you'll still need h.Add

Nope,
the collection stores objects (defined by class module)
