Make sure you copy all of the fields from the footers. Either copying the entire paragraph in each footer (they have different field coding for each Section) or telling Word to display the field codes (which you could do via Alt-F9) will make that easier.

Thank you for trying to help me.
In Section 1 of my document I have only 1 page.
In the first page of Section 2 of my document I insert in the footer your code:
{={PAGE}+{Section 1}}
It should be 2 in my case, instead it gives a syntactical error

I'm still asking whether the code { SECTION} in the body of your document is mandatory.
