Updating multiple pivot tables on one worksheet only

Hi I have the following VBA code which works across every worksheet in my workbook, however I only want it to work on one specific worksheet and don't know how to amend it. Any help greatly appreciated.

Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
On Error Resume Next
Dim wsMain As Worksheet
Dim ws As Worksheet
Dim ptMain As PivotTable
Dim pt As PivotTable
Dim pfMain As PivotField
Dim pf As PivotField
Dim pi As PivotItem
Dim bMI As Boolean

On Error Resume Next
Set wsMain = ActiveSheet
Set ptMain = Target

Application.EnableEvents = False
Application.ScreenUpdating = False

For Each pfMain In ptMain.PageFields
    bMI = pfMain.EnableMultiplePageItems
    For Each ws In ActiveWorkbook.Worksheets
        For Each pt In ws.PivotTables
            If ws.Name & "Sheet2" & pt <> wsMain.Name & "Sheet2" & ptMain Then
                pt.ManualUpdate = True
                Set pf = pt.PivotFields(pfMain.Name)
                        bMI = pfMain.EnableMultiplePageItems
                        With pf
                            .ClearAllFilters
                            Select Case bMI
                                Case False
                                    .CurrentPage = pfMain.CurrentPage.Value
                                Case True
                                    .CurrentPage = "(Sheet2)"
                                    For Each pi In pfMain.PivotItems
                                        .PivotItems(pi.Name).Visible = pi.Visible
                                    Next pi
                                    .EnableMultiplePageItems = bMI
                            End Select
                        End With
                        bMI = False
                
                Set pf = Nothing
                pt.ManualUpdate = False
            End If
        Next pt
    Next ws
Next pfMain
    
Application.EnableEvents = True
Application.ScreenUpdating = True

End Sub
