Hi Paul & Greg,
Thank you both for your responses so far. Unfortunately, although I've tried Paul's edited macro and Greg's alternative macro, they both result in the same problem as before - all paragraphs are renumbered, including those within a list item, whereas I only want to renumber the paragraphs that start [something].[tab], replacing the [something] with a sequential number.
Thanks again in advance,
Paul

***EDIT***

I note that because there is NEVER a full-stop (period) in the middle of a list item, perhaps I could state the problem as "I want to replace the 'word' that preceeds every second full-stop with a sequential number".
