We would like to add an automatically updated date field to show the last time any data has been updated and saved in the program. Our program has 10 tabs and the users may open any tab to work on. Information is automatically obtained from each tab and calculations and summaries are made on the SUMMARY tab.
If someone opens the document but make no saved changes we would like the "Last Updated" field to remain unchanged.
Any assistance that you can give will be appreciated. Thank you.
