My goal is for the footer to be displayed only on the last page automatically.
Indeed, when I have only one page, the footer is displayed, since it is the last page.

However, with each new document creation from this template, I don't know the exact final page count. It is normally between 10 and 15 pages. That's why it must be done automatically with this formula or with vba code (I didn't find an auto solution in vba)
