Macro To Clear Certain Data Across Many Sheets

I have written code to clear data from row 4 onwards and to include columns A:B, C:D only and to ignore the last three sheets

I only need to data clear up to o1 row before where "Total" appears in Col A



However, when activating the code , I get a message compile error: Invalid next control variance reference and next I is highlighted

Your assistance in resolving this is most appreciated

Code:

---

Sub Clear_data()
Dim i As Long
For i = 1 To Worksheets.Count - 3

Dim MyBook As Workbook
Dim Sht As Worksheet
Dim RangeToErase As Range
Dim YTDTotal As Range
Set MyBook = ThisWorkbook
For Each Sht In MyBook.Worksheets
Set YTDTotal = Sht.Range("A:A").Find("Total")
 With Worksheets(i)
        LR = .Range("A" & Rows.Count).End(xlUp).Row
        End With
        If Not YTDTotal Is Nothing Then
            Sht.Range("A4:b" & YTDTotal.Row - 1).Clear
            Sht.Range("D4:D" & YTDTotal.Row - 1).Clear
        End If
        Next i
Next Sht
End Sub

That is because the "Next i" must be after "Next Sht" and not before.

@ Howard please use code tags while posting codes :)
