I have an Excel worksheet that is used as an input/output form over a network. Part numbers are typed in and prices are shown. Calculations are done in a hidden tab and use a database in another hidden tab. Is there a way to set up Excel as an interactive web page so the user will not have access to the other tabs in the sheet? Protecting the tabs alone won't work because they can still save the file to disk. I would like to use this as a web page over an intranet.
