Quiero iterar sobre un archivo de Excel completo.

Sub Rechteck1_KlickenSieAuf()

Dim Zieldatei As String
Dim Line As Integer

'activate and protetct file
    ThisWorkbook.Worksheets(1).Activate
    ActiveWorkbook.Protect

    'Create desired file
    Zieldatei = Application.GetSaveAsFilename(FileFilter:="AVL (*.rtf), *.rtf", InitialFileName:="AVL.rtf")

    'Open desired file
    Open Zieldatei For Output As #1

     With ThisWorkbook.Worksheets(1)

      For Line = 1 To .Cells(.Rows.Count, 1).End(xlUp).Row



           'Write Read-In Data into target data
            Print #1, Join(Application.Transpose(Application.Transpose(.Range(.Cells(Line, 1), .Cells(Line, .Columns.Count).End(xlToLeft)).Value)), "|")


        Next
         End With

    Close #1

    Exit Sub

Este código arroja el mensaje: "tipos incompatibles". No se porque. Agradecería toda ayuda.
