Well I was making pretty good progress today until I used the wrong function and instead of inserting a block of data into a workbook page I deleted and replaced the entire thing. Oops, indeed. Luckily I have a not terribly old backup and most of the work of the last week has been planning or working in a different file. Yes, I have to recreate a lot of the tedious bits that I did yesterday, but at least I know what and where to rebuild and I won't have to spend as much time on it.

I also have a nice new backup in no less than two places.
