Hi Andrew,
I understand that Word has built in indexing functionality, but I was presented with this index by someone who didn't use that, I'd like to help him and also learn a little VBA.

The full story is that pages 29-30 are new so any page number in the index > 28 need to be increased by 2, that includes individual page numbers and page references that span more than 1 page. I'm not experienced enough to decide what to do about the inconsistencies of the roll over digit, seems to me best to just keep the format as it is so
that 298-9 becomes 300-1 and 198-99 becomes 200-01, but I'm looking for the easiest coding solution. Your initial script was a great help and I'll use that as the base for continuing with this project, and appreciate any suggestions you have.
From what I've explained do you think that I can update the index with just Word's built-in wildcard functionality or do I need RexExp?
Thanks for all your help
