Good morning, everyone.

I apologize in advance for the large amount of code, but thank you for taking the time to look through it.

I have a worksheet before double click event set up on a tab called 'BNAGO.' When the user double clicks a Target cell containing a Convention Group name, a new tab is created that shows more information about that Group. A new tab can be created for as many times as there are groups in the Target range. When the new tab is created, I also set some Page Setup properties (this is probably where the slowest part it) so that the workbook is print-ready whenever the users exports the workbook to a PDF. Due to a bug in Excel, i can't set printcommunication to false when I set the header/footer, so that's why they are separated out. The code runs very slowly and I've already had coworkers comment on it.

Please help!

Code: 
Option Explicit
Option Base 1

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
' This sub allows the user to double click a group name and see additional information about that
' group on another tab.
Dim NewTab As Worksheet
Dim DataRange As Range
Dim IndexArray
Dim i As Long
Dim x As Long
Dim y
Dim RebuildName As String
Dim Sheet As Worksheet
Dim RowVar As Long
Dim FindData
Application.ScreenUpdating = False

Dim ShtNm As Worksheet
Dim ShtCount As Long
ShtCount = 0

'check to see if the 4 main sheets exist. If not, then exit the sub. This section prevents the code from firing if saved in a new workbook
For Each ShtNm In Worksheets
    If ShtNm.Name = "DATA" Or ShtNm.Name = "Version Info" Or ShtNm.Name = "Filter" Or ShtNm.Name = "BNAGO" Then
        ShtCount = ShtCount + 1
    End If
Next
If ShtCount <> 4 Then
    Exit Sub
End If

A colleague was able to help me find a way around the problem. Instead of creating a new drill-down sheet and formatting it through page-setup every time a Target cell is double clicked, there's a 'Template' sheet that is already formatted that gets copied and renamed. This is much quicker than before. Here's the code in case someone out there has a similar issue.

Code: 
Option Explicit
Option Base 1

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
' This sub allows the user to double click a group name and see additional information about that
' group on another tab.
Dim NewTab As Worksheet
Dim DataSheet As Worksheet
Dim DataRange As Range
Dim IndexArray
Dim i As Long
Dim x As Long
Dim y
Dim RebuildName As String
Dim Sheet As Worksheet
Dim RowVar As Long
Dim FindData
Application.ScreenUpdating = False

Dim ShtNm As Worksheet
Dim ShtCount As Long
ShtCount = 0

'check to see if the 4 main sheets exist. If not, then exit the sub. This section prevents the code from firing if saved in a new workbook
For Each ShtNm In Worksheets
    If ShtNm.Name = "DATA" Or ShtNm.Name = "Version Info" Or ShtNm.Name = "Filter" Or ShtNm.Name = "BNAGO" Then
        ShtCount = ShtCount + 1
    End If
Next
If ShtCount <> 4 Then
    Exit Sub
End If

'unprotect the workbook and sheets
ThisWorkbook.Unprotect ("stars")
Sheets("BNAGO").Unprotect ("stars")
Sheets("Version Info").Unprotect ("stars")
DataSheet.Unprotect ("stars")
Sheets("filter").Unprotect ("stars")
Sheets("Template").Unprotect ("stars")

Set DataSheet = ThisWorkbook.Sheets("DATA")
Set NewTab = Nothing

'take the cell that was double clicked and if there's not already a sheet with that name
'create a new 'drill-down' sheet and format it
    If (Target.Column = 4) And (Target.Row < 42 And Target.Row > 12) And (Target <> "") Then
'remove invalid characters from sheet name
        For x = 1 To Len(Target)
            y = Mid(Target, x, 1)
            If y Like "]" Or y Like "[[]" Or y Like "[*]" Or y Like "/" Or y Like "\" Or y Like "[?]" Or y Like "!" Or y Like "[#]" Then
                RebuildName = RebuildName + "_"
            Else
                RebuildName = RebuildName + y
            End If
        Next
        For Each Sheet In Worksheets
            If InStr(RebuildName, Sheet.Name) Then
            Sheet.Activate
            Cancel = True
            Exit Sub
            End If
        Next
        
        With ActiveWorkbook
            .Sheets("Template").Copy After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count - 3)
            Set NewTab = .Sheets("Template (2)")
        End With
        NewTab.Visible = True

'rename sheet
        If Len(Target) > 31 Then
            NewTab.Name = Left(RebuildName, 31)
        Else
            NewTab.Name = RebuildName
        End If
        Cancel = True
    
'create array of values from 'DATA' tab that correspond to the target group and insert this in the 'drill-down' sheet
    NewTab.Range("A1").Value = Target.Value
    NewTab.Range("A2:A40") = Application.WorksheetFunction.Transpose(DataSheet.Range("A1:AM1"))
    ReDim IndexArray(1 To 39, 1)
    RowVar = Application.WorksheetFunction.Match(NewTab.Range("A1").Value, DataSheet.Range("YrMthBookingPostAsCol"), 0) + 1
    For i = 1 To 39
        IndexArray(i, 1) = DataSheet.Cells(RowVar, i)
    Next
    NewTab.Range("B2:B40") = IndexArray
    
    NewTab.Columns("B:B").EntireColumn.AutoFit
    NewTab.Activate
    End If

'protect the workbook and sheets
ThisWorkbook.Protect ("stars")
Sheets("BNAGO").Protect ("stars")
Sheets("Version Info").Protect ("stars")
DataSheet.Protect ("stars")
Sheets("Filter").Protect ("stars")
Sheets("Template").Protect ("stars")

Application.ScreenUpdating = True
End Sub
