Richard, I agree with simplifying, however, that may not be possible in a corporate environement with numerous documents that use the same template. Without a lot of effort.
The reasoning behind using a reset of the stream by a previous paragraph number is to automate the numbering without human intervention, which clicking on the reset pgf numbering button requires. It is older technology, however, it works and ensures that the renumbering occurs even if you use the content in a different context. But all of this is conjecture when looking at the problem at hand. Your suggestion is right on the money on looking for a numbering sequence that might be resetting the series. Scott
