Always safest to save with a new name at the beginning of the process (and
with the "always kreate a backup" option selected).
Make sure that the worksheet is unprotected, then do the changes you want to
do & save again, then test your changes.
Repeat until satisfied (then protect the worksheet again if appropriate) &
save again.
