[Excel]Excel to open word-file with mail merge

[pverstraten]

I have an Excel-macro which alters a file, saves it and opens a word file, containing a Mail merge, based on the just saved file. But if I run it, it just opens the file, not making the connection. Anyone who can help me with this?

I'd like to open it From Excel, so that the user input is minimal (and therefore less errors).
Code:

Sub Excel_macro()
 '
 ' Excel_macro Macro

 '
 '
 '
 Dim fn_basis As Variant
 fn_basis = "C:\file.csv"
 Workbooks.OpenText Filename:=fn_basis, _
 DataType:=xlDelimited, Semicolon:=True, Local:=True
 ...
 'Opslaan naar bestand
 Dim fn As Variant
 fn = "C:\fileformailmerge.csv"
 Application.DisplayAlerts = False
 ActiveWorkbook.SaveAs Filename:=fn, Local:=True
 ActiveWindow.Close False
 Application.DisplayAlerts = True
 'Openen Word
 Dim objWord As Object
 Set objWord = CreateObject("Word.Application")
 objWord.Visible = True
 objWord.Documents.Open "C:\Mailmerge.docx"
 'Sluiten Excel
 Application.Quit
 End Sub

If I comment out "objWord.Documents.Open "C:\Mailmerge.docx"" the files doesn't get opened, but when I do it manually everything is fine. If ran as the code above, the docx gets opened, but no connection is made.

How can I fix this?
