Macro working despite warning "-2147467259 (80004005)".

I needed a macro that would arrange all the pages of a document in another document in the form of a grid. So I started to program this macro. After finishing I noticed that after performing the task once it threw a warning. But my surprise was bigger when I saw that if I debugged and pressed f5 it continued perfectly until the next cycle.

the code:

Sub documentTeTeEse()

  Dim DocO As Document
  Set DocO = ActiveDocument
  ancho = DocO.ActivePage.SizeWidth
  alto = DocO.ActivePage.SizeHeight
  iter = DocO.Pages.Count
  If iter < 10 Then
    maxx = iter * ancho
  Else
    maxx = ancho * 10
  End If
  maxy = RoundUp(iter / 10) * alto
  Dim DocN As Document
  Set Propi = CreateStructCreateOptions
  With Propi
    .Name = DocO.Name + " - Grid"
    .PageWidth = maxx
    .PageHeight = maxy
    .Resolution = 300
    .Units = DocO.Unit
  End With
  Set DocN = Application.CreateDocumentEx(Propi)
  DocN.ReferencePoint = cdrTopLeft
  DocN.DrawingOriginX = -DocN.ActivePage.SizeWidth / 2
  DocN.DrawingOriginY = DocN.ActivePage.SizeHeight / 2

  For Each p In DocO.Pages
    nombre = p.Name
    x = (((p.Index - 1) Mod 10) * ancho)
    y = -RoundDown((p.Index - 1) / 10) * alto
    p.Layers(2).Shapes.All.Copy
    DocN.Pages(1).Layers(2).Paste
    ActiveSelection.Group.Name = nombre
    ActiveSelection.PositionX = x
    ActiveSelection.PositionY = y
  Next p
End Sub

how could I disable the warning -2147467259 (80004005) or prevent it from coming up.
