To prevent users unhiding sheets protect the workbook. From the Menus
ToolsProtectionProtect Workbook. Add a password.

To have certain cells on a sheet unlocked and others locked, select the
cells you want to unlock (by default all cells are locked). Then
FormatCellsProtection Uncheck Locked. Then ToolsProtectionProtect
Sheet. Add a password.

Note this will prevent the average user from making unwanted changes.
Anybody a bit more determined will be able to crack the workbook and
worksheet protection passwords.

Hope this helps
Rowan

thanks
don't you mean the default for cells is "unlocked"?

Is it possible to hide sheets but prevent users from just unhiding them
from the Excel main menu? either they can't do it or need a password for
example?

Likewise, what is the correct way to lock off cells in different sheets
so that only certain cells accept data and the user can't just unlock the
other cells
