Hi guys,

I've got a beautifull code that works perfect for sending a workbook. Now I want to copy a module from my source book to the destination workbook but it doesn't succeed : ( the module that I want to copy is module 10 (sub check_files). Please help. Below the code:

Sub Mail_Range()
    Dim Source As Range
    Dim Dest As Workbook
    Dim wb As Workbook
    Dim TempFilePath As String
    Dim TempFileName As String
    Dim FileExtStr As String
    Dim FileFormatNum As Long
    Dim OutApp As Object
    Dim OutMail As Object

    Set Source = Nothing
    On Error Resume Next
    Set Source = Range("A:O").SpecialCells(xlCellTypeVisible)
    On Error GoTo 0

    If Source Is Nothing Then
        MsgBox "The source is not a range or the sheet is protected, please correct and try again.", vbOKOnly
        Exit Sub
    End If

    With Application
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    Set wb = ActiveWorkbook
    Set Dest = Workbooks.Add(xlWBATWorksheet)

    Source.Copy
    With Dest.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial Paste:=xlPasteValues
        .Cells(1).PasteSpecial Paste:=xlPasteFormats
        .Cells(1).PasteSpecial Paste:=xlPasteValidation
        .Cells(1).Select
        Application.CutCopyMode = False
        
    Rows("1:1").Select
    Selection.RowHeight = 15
    Columns("M:M").Select
    Selection.ColumnWidth = 27
    
    Range("M3").Select
    
    With ActiveSheet.PageSetup
     .Orientation = xlLandscape
     .Zoom = False
     .FitToPagesWide = 1
     .FitToPagesTall = False
         
    End With
End With
    

    

    TempFilePath = Environ$("temp") & "\"
    TempFileName = "file" & " " & Format(Now, "dd-mmm-yy")

    If Val(Application.Version) < 12 Then
        'You use Excel 97-2003
        FileExtStr = ".xls": FileFormatNum = -4143
    Else
        'You use Excel 2007-2013
        FileExtStr = ".xlsx": FileFormatNum = 51
    End If

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    With Dest
        .SaveAs TempFilePath & TempFileName & FileExtStr, FileFormat:=FileFormatNum
        On Error Resume Next
        With OutMail
            .To = ThisWorkbook.Sheets("amount").Range("P6").Value
            .SentOnBehalfOfName = """
            .CC = ""
            .BCC = ""
            .Subject = ""
            .Body = ""
            .Attachments.Add Dest.FullName
            'You can add other files also like this
            '.Attachments.Add ("")
            .Display   'or use .Send
        End With
        On Error GoTo 0
        .Close savechanges:=False
    End With

    Kill TempFilePath & TempFileName & FileExtStr

    Set OutMail = Nothing
    Set OutApp = Nothing

    With Application
        .ScreenUpdating = True
        .EnableEvents = True
    End With
End Sub
