Tell us the exact steps you go through to do the copy and we can guess at
what went wrong.

Every month I copy the monthly sheet (i.e. September) and then create a new
sheet (i.e. October). I then do all changes that need to be made. However,
when I copied the September over and renamed it October, about sixty rows
were missing. They were not consecutive rows and they were not hidden. They
just disappeared.

I am not sure what happened to them and how to make sure that it doesn't
happen again. Fortunately, my editor had the correct version but I still had
several hours worth of work trying to duplicate the October sheet correctly.
This happened to two different files. Can anyone tell me what could have
possibly happened and how to fix it?
