Your right it does what I asked for, but not what I needed.
I have a master spreadsheet that I am updating throughtout the day
every couple of hours I save the master to disk, delete unneeded row for the sales department, save it as 'sell.xls' close sell.xls and reopen master.
I was looking for a quicker way to do this in a macro, something like:
Save the master to disk, open a copy and call it sell.xls, make changes to it and save it - all without having to reload the master.
