Word create or open with VBA functionality?

[phbench]

If I am thinking about this in the wrong way do not hesitate to say. I am new to VBA but I am not new to programming. I want to be able to automate the creation of Word documents. That is when the document does not exist already. If the document exists, I would like just to open it.
Where I am running into problems is when I use a *.dotm to do the creation, it works well with the VBA programming I am learning. However, if the document exists, I want to open it with the VBA programming functionality I have programmed into the original template. I make this a point because when I launch a document without the VBA template it does not have the functionality I desire.
For now, when I use some logic to just open it, VBA creates an additional document. I am sure this is because it is the normal way a *.dotm works. Besides the creation of the other unneeded document, it allows my document (SJUpaper01.docx) opened version to have the functionality I desire.
Here is some of the VBA code I am having success with –

Sub NewOrOpenDoc()
    Dim h2nWrd As String
    Dim fso As Object
    Set fso = CreateObject("Scripting.FileSystemObject")
    Let h2nWrd = "D:/Stuff/VBA/Test/SJUpaper01.docx" ' Let to assign data variable although not nessicary
    If fso.FileExists(h2nWrd) Then
        Documents.Open FileName:=h2nWrd
    Else
        ActiveDocument.SaveAs2 FileName:=h2nWrd, _
        FileFormat:=wdFormatDocumentDefault
    End If
End Sub

SJUpaper01.docx is the name I will eventually populate dynamically each time I launch from the *.dotm template. For now, it is the document I am testing with. Could someone suggest a way to do this? Thanks
