Sorry, can't open files here.
You maybe better explain what you need.
If paragraphs are already selected (continuous selection), and you want to format them all at once, then use:
Code:
With Selection
.Font.Bold = True
End With
If you want to format only the 1st paragraph of the selection (not need to be the 1st paragraph of the document):
Code:
With Selection.Paragraphs(1).Range
.Font.Bold = True
End With
If you want to format only the 1st paragraph of the activedocument (not the selection)
Code:
With Activedocument.Paragraphs(1).Range
.Font.Size= 20
End With
