Can't pass string into array function : subscript out of range - arrays

Question

I'm trying to imitate copying multiple sheets to a new workbook and this is fine if I literally use the sheet names in the array function.
However if I try to pass a string variable into the array I get a subscript out of range error.
The line of concern is:
Wb.Sheets(Array(SheetsArray)).Copy After:=RegionWb.Sheets(RegionWb.Sheets.count)
Please see my code below :
Sub CreateFiles()
Application.ScreenUpdating = False
Dim LastRow As Long
Dim WKC As String: WKC = Replace(DateValue(DateAdd("ww", -1, Now() - (Weekday(Now(), vbMonday) - 1))), "/", ".")
Dim FilePath As String: FilePath = "Z:\MI\Krishn\Retail"
Dim BuyerLastRow As Long
Dim Wb As Workbook: Set Wb = ActiveWorkbook
Dim RegionWb As Workbook
Dim RegionCount As Integer
Dim RegionCounter As Integer
Dim SheetsArray As String
With BuyerList
LastRow = .Range("G1048576").End(xlUp).Row
BuyerLastRow = .Range("A1048576").End(xlUp).Row
'Create WKC Dir
If Dir(FilePath & "\" & WKC, vbDirectory) = "" Then
MkDir FilePath & "\" & WKC
End If
'Create Create Files
If CountFiles(FilePath & "\" & WKC) = 0 Then
For i = 2 To LastRow
RegionCounter = 0
SheetsArray = ""
' Set RegionWb = Workbooks.Add
' 'wb.SaveAs FilePath & "\" & WKC & "\" & .Cells(i, 7).Value
' RegionWb.SaveAs FilePath & "\" & WKC & "\" & "WKC " & WKC & " - " & .Cells(i, 7).Value & ".xlsb", 50
For j = 2 To BuyerLastRow
RegionCount = Application.WorksheetFunction.CountIf(.Range("C:C"), .Cells(i, 7).Value)
If .Cells(i, 7).Value = .Cells(j, 3).Value Then
SheetsArray = SheetsArray & """" & .Cells(j, 2).Value & ""","
RegionCounter = RegionCounter + 1
If RegionCounter = RegionCount Then
Debug.Print Left(SheetsArray, Len(SheetsArray) - 1)
Set RegionWb = Workbooks.Add
RegionWb.SaveAs FilePath & "\" & WKC & "\" & "WKC " & WKC & " - " & .Cells(i, 7).Value & ".xlsb", 50
'Wb.Sheets(Array(Left(SheetsArray, Len(SheetsArray) - 1))).Copy After:=RegionWb.Sheets(RegionWb.Sheets.count)
SheetsArray = Left(SheetsArray, Len(SheetsArray) - 1)
Wb.Sheets(Array(SheetsArray)).Copy After:=RegionWb.Sheets(RegionWb.Sheets.count)
'Wb.Sheets(Array()).Copy After:=RegionWb.Sheets(RegionWb.Sheets.count)
RegionWb.Save
RegionWb.Close
Exit For
End If
' Wb.Sheets(Wb.Sheets("Buyer list").Range(Cells(j, 2).Address).Value).Copy After:=RegionWb.Sheets(RegionWb.Sheets.count)
End If
Next j
'
'
Next i
End If
End With
Application.ScreenUpdating = True
End Sub

You can split the string into an Array like this:
Wb.Sheets(Split(SheetsArray, ",")).Copy After:=RegionWb.Sheets(RegionWb.Sheets.Count)
As GSerg pointed out: You'll need to remove the quotes around the Worksheet names.
SheetsArray = SheetsArray & .Cells(j, 2).Value & ","
The backslash would be a safer delimiter that using a comma because Worksheet names can include a comma but not a backslash.
SheetsArray = SheetsArray & .Cells(j, 2).Value & "/"
Wb.Sheets(Split(SheetsArray, "/")).Copy After:=RegionWb.Sheets(RegionWb.Sheets.Count)
