Deleting an empty page

I've encountered a problem once in a while when finishing and getting ready to print a word document: I have gotten an extra blank page at the end of the document. Usually I can delete the extra page by using the "delete" or "backspace" keys, but sometimes that doesn't work! After we talked about the different "view" layouts, I tried changing from "print layout" to "normal" and was able to delete the extra page!
