As for the checkbox (included specific paragraphs). That depends on the strategy you use. One is to just include everything in the template and then delete the pieces you don't want:
Code:
Sub ScratchMacro()
'A basic Word macro coded by Greg Maxey
Dim bCheckTarget1 As Boolean 'Simulates a checkbox value
Dim oRng As Range
bCheckTarget1 = False
If Not bCheckTarget1 Then
Set oRng = ActiveDocument.SelectContentControlsByTitle("Target1").Item(1).Range
ActiveDocument.SelectContentControlsByTitle("Target1").Item(1).Delete True
oRng.Paragraphs(1).Range.Delete
End If
lbl_Exit:
Exit Sub
End Sub
