adding a summary sheet in every workbook

hi im trying to loop through all my workbooks in my folder and adding a summary sheet as the first sheet if there isn't one in the workbook, the problem is that instead of adding the summary sheet, it is just renaming the first sheet "Summary". Is there anything i can do ? Thanks in advance !

Below is my code, it is to select the folder i want and loop through every workbook and check if there is a "Summary" page, if there isn't it is to copy the first sheet of the workbook and rename it to "Summary". But right now it is jus rename the first sheet to "Summary".

Private Sub CommandButton1_Click()
Dim wb As Workbook
Dim myPath As String
Dim myFile As String
Dim myExtension As String
Dim FldrPicker As FileDialog
Dim ws As Worksheet



'Optimize Macro Speed
  Application.ScreenUpdating = False
  Application.EnableEvents = False
  Application.Calculation = xlCalculationManual

'Retrieve Target Folder Path From User
  Set FldrPicker = Application.FileDialog(msoFileDialogFolderPicker)

    With FldrPicker
      .Title = "Select A Target Folder"
      .AllowMultiSelect = False
        If .Show <> -1 Then GoTo NextCode
        myPath = .SelectedItems(1) & "\"
    End With

'In Case of Cancel
NextCode:
  myPath = myPath
  If myPath = "" Then GoTo ResetSettings

'Target File Extension (must include wildcard "*")
  myExtension = "*.xls*"'Target Path with Ending Extention
  myFile = Dir(myPath & myExtension)

'Loop through each Excel file in folder
  Do While myFile <> ""'Set variable equal to opened workbook
      Set wb = Workbooks.Open(Filename:=myPath & myFile)

    'Ensure Workbook has opened before moving on to next line of code
      DoEvents

    'adds summary page

      If wb1.Sheets(1).Name <> "Summary" Then
        wb1.Sheets(1).Copy before:=Sheets(1)
        ActiveSheet.Name = "Summary"

        Else


      End If


    'Save and Close Workbook
      wb.Close SaveChanges:=True

    'Ensure Workbook has closed before moving on to next line of code
      DoEvents

    'Get next file name
      myFile = Dir
  Loop

'Message Box when tasks are completed
  MsgBox "Task Complete!"

ResetSettings:
  'Reset Macro Optimization Settings
    Application.EnableEvents = True
    Application.Calculation = xlCalculationAutomatic
    Application.ScreenUpdating = True
