Security Issue between Versions

[Sunsetsuperman]

To make a long story short I am trying to work with our Quality department to
get all of our quality records available on a shared drive. To do this we
need to make sure that they cannot be modified. Currently Office 2003
(specifically Excel) has the security needed to prevent users from copying
the form to another Excel worksheet or workbook and making modifications.
However, if the same file is opened in an earlier version of Excel, the same
security does not function and the cells can be copied and then modified. Is
there a way i can prevent this from happening with out having to upgrade
everyone to excel 2003?

Thank you
