Populate UserForm List Box with Paragraph Text from MS Word Range

Hi All

Seasons Greetings :-D

I am struggling with something that I thought would be close to simple...  Populate a userform listbox with text from a specified range in a document.  Each entry should be a single paragraph...  (ideally I'd also like the paragraph number to show up; I'm using a list style).

Private Sub UserForm_Initialize()  '  <<<< code in user form (UF)
Dim iRng As Range  ' this is defined by a bookmark
Dim parra As Paragraph
Dim pText As String

With ActiveDocument
Set iRng = ActiveDocument.Bookmarks("iTxt").Range   ' works, the range is selected
iRng.Select
For Each parra In iRng   ' <<<<  No matter what I do here the code fails with an unhelpful message
pText = parra.Range.Text
 RefListBox.AddItem (pText)

Next parra
 
End With
End Sub

There is a sub to call this...

Sub myUF()
UF.Show

End Sub

The error message is:
Run-time error '438'
Object doesn't support this property or method

When I try to debug the line UF.show is higlighted...
