copy values in different worksheet in one single worksheet

Hell everybody, I need help to fix the problem. I hope that somebody could solve the small problem.

The first part import the columns of the selected *.csv files in different worksheet. The second part copy the columns of each worksheet in the same worksheet but in the SAME column. I would have only the 2nd column of each worksheet in different colmuns in the worksheet.

Option Explicit
Sub importCSV()
Dim oeffnen, n As Integer
Application.ScreenUpdating = False
oeffnen = Application _
.GetOpenFilename(fileFilter:="Text Files (*.csv), *.csv", MultiSelect:=True)
If IsArray(oeffnen) = False Then GoTo ENDE
For n = 1 To UBound(oeffnen)
Workbooks.OpenText oeffnen(n)
ActiveWorkbook.Sheets(1).Copy After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count)
Workbooks(Mid(oeffnen(n), InStrRev(oeffnen(n), "\") + 1)).Close False
Next n
ENDE:
Application.ScreenUpdating = True

Dim J As Integer

On Error Resume Next
Sheets(1).Select
Worksheets.Add ' add a sheet in first place
Sheets(1).Name = "Combined"

' copy headings
Sheets(2).Activate
Range("A1").EntireRow.Select
Selection.Copy Destination:=Sheets(1).Range("A1")

' work through sheets
For J = 2 To Sheets.Count ' from sheet 2 to last sheet
Sheets(J).Activate ' make the sheet active
Range("A1").Select
Selection.CurrentRegion.Select ' select all cells in this sheets

' copy cells selected in the new sheet on last line
Selection.Copy Destination:=Sheets(1).Range("A65536").End(xlUp)(2)
Next
End Sub

Thank you in advance
