Cannot attach workbook to send by vba button - vba

Question

I have some vba code, which I have attached to a excel button. When pressing the button the outlook mail box will appear- ready to send the mail. But for some reason the workbook is not attached to the mail. In the code below - I think something is wrong with add.attachments. at the end
My VBA code is:
Dim xRg As Range
Private Sub Worksheet_Change(ByVal Target As Range)
On Error Resume Next
If Target.Cells.Count > 1 Then Exit Sub
Set xRg = Intersect(Range("D7"), Target)
If xRg Is Nothing Then Exit Sub
If IsNumeric(Target.Value) And Target.Value > 200 Then
Call Mail_small_Text_Outlook
End If
End Sub
Sub Mail_small_Text_Outlook()
Dim xOutApp As Object
Dim xOutMail As Object
Dim xMailBody As String
Set xOutApp = CreateObject("Outlook.Application")
Set xOutMail = xOutApp.CreateItem(0)
xMailBody = "Hi there" & vbNewLine & vbNewLine & _
"This is line 1" & vbNewLine & _
"This is line 2"
On Error Resume Next
With xOutMail
.To = "Email Address"
.CC = ""
.BCC = ""
.Subject = "send by cell value test"
.Body = xMailBody
.Attachments.Add "W\Desktop\Files\Workbook1
.Display 'or use .Send
End With
On Error GoTo 0
Set xOutMail = Nothing
Set xOutApp = Nothing
End Sub

Answer 1

The following line of code is not complete:
.Attachments.Add "W\Desktop\Files\Workbook1
The Add method of the Attachments class creates a new attachment in the Attachments collection. The source of the attachment can be a file (represented by the full file system path with a file name), for example:
.Attachments.Add "C:\Test.xslx", olByValue, 1, "Test"
I'd also suggest specifying a local file path.
