Copy content from closed work book column - vba

Question

As said in the title I'm trying to copy data from a column into a new workbook as its a weekly report where the data I add in this column remains valid.
Sub copyColData00()
Dim lastRow As Long
Dim myApp As Excel.Application
Dim wkBk As Workbook
Dim wkSht As Object
Dim mnt As String
Set myApp = CreateObject("Excel.Application")
mnt = InputBox("Enter Filename")
Set wkBk = Workbooks.Open("\\n\Documents\" & mnt & ".xlsx")
lastRow = wkBk.Sheets(1).Range("R" & Rows.Count).End(xlUp).Row
wkBk.Sheets(1).Range("R1:R" & lastRow).Copy
myApp.DisplayAlerts = False
wkBk.Close
myApp.Quit
Set wkBk = Nothing
Set myApp = Nothing
Set wkBk = ActiveWorkbook
Set wkSht = wkBk.Sheets("Sheet1")
wkSht.Activate
Range("R1").Select
wkSht.Paste
Exit Sub
End Sub
My problem is that I want it to past it directly while there I get a prompt that ask if I want to copy all the data in the clip board or not and my second problem is that at
Set wkSht = wkBk.Sheets("Sheet1")
It gives me the error subscript out of range I've trouble understanding what happens there if someone could help it would be nice!

This is a lot easier way to do that:
Sub copyColData00()
Dim lastRow As Long
Dim wkBk1 As Workbook, wkBk2 As Workbook
Dim wkSht As Object
Dim mnt As String
mnt = InputBox("Enter Filename")
Set wkBk1 = ActiveWorkbook
Set wkBk2 = Workbooks.Open("\\n\Documents\" & mnt & ".xlsx")
lastRow = wkBk2.Sheets(1).Range("R" & Rows.Count).End(xlUp).Row
wkBk1.Sheets(1).Range("R1:R" & lastRow).Value = wkBk2.Sheets(1).Range("R1:R" & lastRow).Value 'change which sheet you want for wkBk1
wkBk2.Close
End Sub
