[RESOLVED] Problem with VB6 and Excel

[Bahy]

Hi all!
What i am trying to do is to insert some columns on the left side of the D column. But i was stuck in the error number 1004. And i really don't know how to debug.
My codes are below

  Set xlsApp = New Excel.Application
        Set xlsWkb = xlsApp.Workbooks.Open(filename)
        Set xlsSht = xlsWkb.Sheets(1)
        
        tenTemp = xlsSht.Name
        
        With xlsSht
            .Rows("1:5").Delete
            .Columns("D:e").Select
            .Columns.Insert Shift:=xlToRight
end with

The error was flagged right on the line of the Insert method.
If anyone have done this before, please tell me how to debug this.

Thank you so much.
