Add footer text and page numbers to Word documents

Hi all, I have a Word document that has a lot of sections, some of which are in the portrait layout, while others are in the landscape layout.

I want to add some text ("For Internal Use Only") in the center of the footer, and page numbers in the right of the footer. I have some basic VBA skills. I tried to record a macro, but I wasn't able to add the footer I want while recording the macro. Can anyone help me?

I figured it out myself. This thread can be closed. Thanks.
