Modification of macro to clear not delete page.

Hi All,

I have a macro that I found on the net for copying a filtered selection and copying to a new sheet. Works great and thanks very much to the donor. I would like to alter it slightly so that it just clears the sheet called 'Interval tasks' instead of deleting it and creating a new one. Here is the code:

Sub Copy_With_AutoFilter1() 'This code filters the task list by the true statement that is the outcome of the
                            'calender time selected by the task resource userform.  It then creates a new sheet
                            'called Interval Tasks

    Dim WS As Worksheet
    Dim WSNew As Worksheet
    Dim rng As Range
    Dim rng2 As Range

    With Application
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    'Name of the worksheet with the data
    Set WS = Sheets("All Tasks")  '<<< Change

    'Set filter range : A1 is the top left cell of your filter range and
    'the header of the first column, D is the last column in the filter range
    Set rng = WS.Range("A1:U" & Rows.Count)

    'Firstly, remove the AutoFilter
    WS.AutoFilterMode = False

    'Delete the sheet MyFilterResult if it exists
    On Error Resume Next
    Application.DisplayAlerts = False
    Sheets("Interval Tasks").Delete
    Application.DisplayAlerts = True
    On Error GoTo 0

    'This example filters on the first column in the range (change the field if needed)
    'In this case the range starts in A so Field:=1 is column A, 2 = column B, ......
    'Use "<>Netherlands" if you want the opposite
    rng.AutoFilter Field:=21, Criteria1:="=True"

    'if you want to filter on a cell value you can use this, use "<>" for the opposite
    'This example uses the activecell value
    'rng.AutoFilter Field:=1, Criteria1:="=" & ActiveCell.Value

    'This will use the cell value from A2
    'rng.AutoFilter Field:=1, Criteria1:="=" & WS.Range("A2").Value

    'Add a new worksheet to copy the filter results in
    Set WSNew = Worksheets.Add
    WSNew.Name = "Interval Tasks"
    WSNew.Move after:=ThisWorkbook.Sheets("Charts")
    
    Call FormatIntervals
    

    'Copy the visible data and use PasteSpecial to paste to the new worksheet
    WS.AutoFilter.Range.Copy
    With WSNew.Range("A2")
        ' Paste:=8 will copy the columnwidth in Excel 2000 and higher
        .PasteSpecial Paste:=8
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
        .PasteSpecial xlPasteFormulas
        .Sort Key1:=Range("N2"), Order1:=xlAscending, Header:= _
        xlGuess, OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom
        Application.CutCopyMode = False
        .Select
    End With
    'Close AutoFilter on original sheet
    WS.AutoFilterMode = False

    With Application
        .ScreenUpdating = True
        .EnableEvents = True
    End With
    Call SortandFilter

End Sub

I have had a couple fo attempts to do it but so far no luck. Can anyone help?

Many thanks,
JD
