I found a great piece of coding in the archives for taking care of filters
in protected workbooks. My difficulty lies in that the sheets all have
different names and I don't know how to code for all sheets in a workbook.

Here's the code to put in the workbook module:

Private Sub Workbook_Open()
Worksheets("Sheet1").Activate
ActiveSheet.EnableAutoFilter = True
ActiveSheet.Protect UserInterfaceOnly:=True
End Sub

I'm guessing that it's the "Sheet1" that is stopping this from working.
I've tried removing the "Sheet1", etc., but all I get are errors. Is there
a way to modify the above so that it works on any sheet?: Users will be
adding new ones in the future and they'll call them all sorts of things that
would be impossible to determine in advance so a generic bit of code would
work best.

Thank you! :oD
