>Are you sure that node exist? When you remove some node, other nodes' indexes shifted. So last node index no longer valid.

I would think so. It errors on the first time through the loop, before anything gets deleted.

So if the indexes change how would I do it? Just keep using the FirstSibling index until Children returns .F.?
