Sorry Bob, I must admit that I am not that good at
explaining, but here is another go-
Yes I would need the tabs to change back to there
previous names, which were 20, 21, 22, and so forth to 40
as the book closes down, ready to be used again the next
time it opens.
The workbook will be used for importing the data into
AutoRoute, and that is why I needed the tabs names to
change to make it easier to see what sheets / data are
being imported.
Once the workbook is complete, it would be used by a
dozen other people, and rather the risk of them saving
changes, it would automatically reset on close down, and
of course add a button in case any mistakes are made
whilst open.
