Hi everyone,

I'm having an issue with a VBA script originally written by forum member dmt32, which I'm successfully using on a couple of my spreadsheets, but I've run into a problem with it on my current project. The VBA uses a table created by the script to specify users who are able to access specific sheets in the workbook, and with a couple of slight tweaks also enables the sheet protection to stop users accidentally overwriting formulas etc. This has worked fine on my other projects, but I've hit a snag with this one because most of the sheets have slicers/pivot tables/timelines, and when the various macros run, while it protects everything that needs protecting, it's also locking the slicers/pivot tables/timelines.

These two threads provide the background to me using the VBA code:
  • Password protect viewing for multiple worksheets: Password Protect Viewing for Multiple Worksheets
  • Protecting pages from viewing using network username:

...and this is the code I'm using:

               If Len(shPassword) > 0 Then sh.Protect Password:=shPassword
            End If
    Next sh
End Sub

When I set the sheet protection manually while putting together the workbook, so the slicers, pivot table and timeline would still function, on the list of actions all users are allowed to do, I selected:
  • Select locked cells
  • Select unlocked cells
  • Sort
  • Use Autofilter
  • Use PivotTable & PivotChart
  • Edit objects
This allowed the sheets to be locked, but the users still to filter and use the slicers, pivot table, and timeline.

My question is, is there a way to get the VBA to specify that these options should be allowed? My VBA skills are 'just enough to be dangerous!' ;) I know enough to understand what it's doing when I see it, and to be able to make very minor tweaks, but not enough to write it myself.

(btw, if it's relevant I'm using Office 365)

Thanks,

Bliss
