VBA：代码在sheet（）。delete之后停止执行

Question

我有这段代码，我从表格中获取数据＆＃34;数据＆＃34;并将其移动到其他工作表（目的地）。但是，出于某种原因，当代码到达＆＃34;数据＆＃34;的删除面时代码停止执行。代码实际上删除了＆＃34;数据＆＃34;但是没有任何反应......上个月这个执行完美，而且总是有。它可能是我的Excel 2010设置，权限或我的代码错误（虽然它看起来正确）...

     Public Function backupfunction(PathName, UnderPath, FileName)

'Find date
dato = Range("datecell").Value

'open file     
Workbooks.Open FileName:=PathName & UnderPath & FileName & ".xlsb"

'Backup of file
ActiveWorkbook.SaveAs FileName:=PathName & "history\" & date & "\" & UnderPath & FileName & " " & dato & ".xlsb"
',FileFormat:=xlExcel12,CreateBackup:=False

  'Move data from sheet "data" over to destination sheets
    Sheets("D.FF").Range("A3:D1000").ClearContents
    Sheets("data").Activate
    Range("J2:M2").Select
    Range(Selection, Selection.End(xlDown)).Copy
