How would I make it so that only certain users in our network could access my spreadsheet to edit and all others would only have read only access? I have about 10 supervisors that need access for each spreadsheet. All the other supervisors and officers need to be able to look to see what is completed, but dont need to edit. I already have a macro that protects each sheet upon close so that cells with formulas dont accidentally get changed and it is not accidentally left unprotected. Could somebody help me out with a macro to pick out the user names that need access and make it read only for everybody else? This would allow the supervisors quick access to input the qual dates, but the protection would keep them from messing up formulas inadvertantly. The Admin(s) would be the only one that would need to get in and change any of the formulas and make any major changes to the sheet.
