Unable to set the visible items of the Pivot Table

I have the code below, which I've been using for over a year to determine the items to show on my pivot table. The code is repeated 12 different times for 12 different Expense Detail files every morning. This morning, the code started displaying the "Unable" message at the line "PI.Visible = True" on one specific Expense Detail report. I can't see anything different with this expense detail report; it DOES have a "PROJECTED" column, and if I stop the code at the error and refresh the table it all appears just as it should, with "PROJECTED" hidden. Here's my tried and true code:

'Change this to determine what options you want to show/hide
        With PT.PivotFields("MOS2")
            For Each PI In PT.PivotFields("MOS2").PivotItems
                If PI = "PROJECTED" Then
                    PI.Visible = False
                Else
                    PI.Visible = True
                End If
            Next
        End With

I tried a change to see if this would work better. Same problem.

'Change this to determine what options you want to show/hide
        With PT.PivotFields("MOS2")
            For Each PI In PT.PivotFields("MOS2").PivotItems
                If PI <> "PROJECTED" Then
                    PI.Visible = True
                Else
                    PI.Visible = False
                End If
            Next
        End With

Any help with troubleshooting this one is greatly appreciated.

Arlu,
Thanks for reminding me of past glories. I didn't try the "Compare Text" option (but should have!), but I did check to make sure the "PROJECTED" was the same in all instances, and it was. I still don't know why it caused a problem, but I fixed it by altering my code like this:

 'Change this to determine what options you want to show/hide
        With PT.PivotFields("MOS2")
            For Each PI In PT.PivotFields("MOS2").PivotItems
            
                If PI = "PROJECTED" Then
                    PI.Visible = False
                End If
            Next
            
        End With

Since earlier in my code I call the pivot table to show all, all I really needed to do at this step was to turn off the "PROJECTED". I haven't closed the thread yet because I want to run it tomorrow morning to make sure it's working correctly.

Thanks Paul; I had noticed that before, and thought I changed it, but sure enough I didn't. I appreciate the help.
