Page Numbers adding pages

[jbeck2862]

How do I get word to add pages numbers without adding pages? When i add page numbers at the bottom of the page (page X of Y) my two page document turns into three pages with only one line of text on the third page. I can clearly see that there is ample room for the page numbers before I add them. I would like to possibly add the page numbers in front of the text/images without adding a header and or footer.
