Here's a problem with generating an index in the format I want in FrameMaker
5.5.6 (UNIX). I haven't seen any reference to this being a known bug, which is why I'm asking here.

I have a book split into chapters (chapter I, II, III etc). The page numberingm in the chapters starts at 1 for each chapter. Therefore, in the index, I need to have page numbers displayed as II-32, for example. For this, I use in the index reference page, <$paranumonly[ChapterTitle]> - <$pagenum>.

This is ok, until I have figures or bulleted lists, in which case the index picks up _their_ numbering, not that of the chapter. It seems that FrameMaker is picking up the numbering of the first previous numbered paragraph it finds, regardless of whether it is of the correct type (ChapterTitle).

Am I doing something wrong, or is this a bug, in which case, is there a known
workaround?

Thanks,
Iain
