ooooh! it's working! that's perfect

What do you mean "such method in the word object"?

So if i understand well
you created a variable call "oRng" as a range (range in order to set the bookmark inside? it will define an area instead of a value isn't it?)
Then you set the oRng as datepp
and you insert in the date inside orng with oRng.Text = format ...

I dont understand the activedocument.bookmarks.add "datepp", orng = is it to add back the bookrmarks ?
