我收到以下代码的“应用程序定义或对象定义对象错误”
10 Sheets("Main").Select
20 currYearDate = DateValue("April 1, " & Year(Now))
30 nextYearDate = DateValue("March 31, " & (Year(Now) + 1))
40 Range("H9").Activate
50 With ActiveCell.Validation
60 .Add Type:=xlValidateDate, AlertStyle:=2, Operator:=1, Formula1:=currYearDate, Formula2:=nextYearDate
70 .ErrorMessage = "You should enter date between " & Format(DateValue("April 1," & Year(Now)), "dd-mmm-yyyy") & " and " & Format(DateValue("March 31," & Year(Now) + 1), "dd-mmm-yyyy")
80 .ErrorTitle = "Warning Message"
90 End With
有人可以帮帮我吗?
