I believe that we are counting in opposite directions. In the way I was counting the 0th parent would be the current tiddler.
The biggest problem I can see with what you are suggesting where the 0th parent is the outermost tiddler is that the numbering changes when you transclude a tiddler. If you don't have your indexing based on the layer where the calling happens than I think it would be very delicate because you couldn't display the tiddler anywhere else without changing the numbering. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
