ahhh Got it. I know why it didn't select the numbers. It's partly my fault. I'm the one that said sentence, but since these are often title line, we could consider them Paragraphs.
So below, instead of :
Code:
oRng.Expand Unit:=wdSentence
I've put :
Code:
oRng.Expand Unit:=wdParagraph
And it worked.
Thank you, case solved
