=INDEX(PeriodList,MonthNo) creating _xlfn.SINGLE name in workbook
问题 I hope someone will be able to help with a problem that has surfaced with a recent Excel update. If I define two range names in an Excel worksheet and then enter =Index(PeriodList,MonthNo) in cell A13 via the UI, I find that Thisworkbook.Names.Count in VBA reports 2 - as expected. However, if I execute Activesheet.Range("A13").Formula = "=Index(PeriodList,MonthNo)" in VBA, Thisworkbook.Names.Count reports 3 and I find that a new name that cannot be deleted is created. The name is _xlfn.SINGLE
