I'm trying to do a project and i want to put in a footer to show the pages. My problem is that the first page will say one, but then i have to put the footer in again on the next page. When i do this, the third page will say two as well. If i change the third page to say 3, the second page will then also say three. How do i get it to automatically change number with each page? I had the exact same problem earlier today on another project but i asked my teacher and he said it didn't matter. My current project will have 20+ pages, so I don't really want to put it in manually. I also don't feel like it would let me anyway, but I haven't tried to do this with more than three pages.
