type mismatch looping through shapes - vba

Question

I'm getting a type mismatch 13 error in the line that loops through the shapes in a slide. I can see that the oSh is Nothing, but if I .Count the shapes, there are plenty of shapes in the slide. How does this make sense?
Brief code:
Dim oPP As PowerPoint.Presentation
Dim oS As Slide
Dim oSh As Shape
For Each oS In oPP.Slides
For Each oSh In oS.Shapes '<-- this line is the error line
On Error Resume Next
If oSh.Type = 14 _
Or oSh.Type = 1 Then
'do stuff
End If
On Error GoTo 0
Next oSh
Next oS
Full code:
Sub PPLateBinding()
Dim pathString As String
'no reference required
Dim PowerPointApplication As PowerPoint.Application
Dim oPP As PowerPoint.Presentation
Dim oS As Slide
Dim oSh As Object
Dim pText As String
Dim cellDest As Integer
Dim arrBase() As Variant
Dim arrComp() As Variant
ReDim Preserve arrBase(1)
ReDim Preserve arrComp(1)
Dim fd As FileDialog
Dim FileChosen As Integer
Dim FileName As String
Dim iPresentations As Integer
Set fd = Application.FileDialog(msoFileDialogFilePicker)
'use the standard title and filters, but change the

'allow multiple file selection
fd.AllowMultiSelect = True
FileChosen = fd.Show
If FileChosen = -1 Then
'open each of the files chosen
For iPresentations = 1 To fd.SelectedItems.Count
'On Error Resume Next
Set PowerPointApplication = CreateObject("PowerPoint.Application")
Set oPP = PowerPointApplication.Presentations.Open(fd.SelectedItems(iPresentations))
If Err.Number <> 0 Then
Set oPP = Nothing
End If
If Not (oPP Is Nothing) Then
cellDest = 0
'We assume PP is already open and has an active presentation
For Each oS In oPP.Slides
'Debug.Print oPP.Slides.Count
If oS.Shapes.Count > 0 Then
Debug.Print oS.Shapes.Count
For Each oSh In oS.Shapes
Debug.Print "hey"
On Error Resume Next
If oSh.Type = 14 Or oSh.Type = 1 Then
pText = oSh.TextFrame.TextRange.Text
ReDim Preserve arrBase(UBound(arrBase) + 1)

'Debug.Print pText
ElseIf (oSh.HasTable) Then
Dim i As Integer
For i = 2 To oSh.Table.Rows.Count

Excel has its own Shape type (which is not the same as PowerPoint.Shape type), so you should change
Dim oSh As Shape
to (for earlier binding)
Dim oSh As PowerPoint.Shape
or (for late binding)
Dim oSh As Object
Also note, if you're going to use powerpoint with late binding (as suggests your function name Sub PPLateBinding()), you should change all types PowerPoint.Something to Object (unless you add reference to powerpoint object model, but in this case I don't see any reason for using late binding).
