Hi John,

Excel security is quite weak, almost any non beginner can bust the password
for a worksheet in just a few minutes. If the co-workers "respect" the fact
the sheet is protected then it may help.

Otherwise don't put anything super secret under worksheet protection.

Tools Protection Protect worksheet enter your password OK out.

Howard

How do you protect all the sheets in a workbook so the user can't enter
something in a cell that has a formula?

Thanks
