Unable to Sort Pages LC

My first suggestion is that you immediately edit your question and delete the Visio diagram. There is way too much confidential information in it. If you can't delete the file, I would delete the entire question just to be sure it's gone, and then post a new question without the attachment.

The problem with the diagram is that all pages from VBackground-1 to the right are background page. I'm not sure how that happened but that's why you can't move any of them (Visio does not allow you to reorder background pages from the user interface.)

If you change the page type of any page to foreground, it will pop to the left of VBackground-1 and you can then move it anywhere you'd like.

You can make this change to each page manually, of course. Of you can use this macro to do it for you:

Sub ChangePageType()
' sets the background page flag off for all pages except the one named VBackground-1

    Dim doc         As Visio.Document
    Dim pg          As Visio.Page
    
    Set doc = ActiveDocument
    
    For Each pg In doc.Pages
        If pg.Name <> "VBackground-1" Then
            pg.Background = False
        End If
    Next pg

End Sub

We can deal with page size and page sequence next.
