Youll find instructions for formatting a running head (page header) in your paper at the link below.
Include a page header (also known as the "running head") at the top of every page. To create a page header/running head, insert page numbers flush right. Then type "TITLE OF YOUR PAPER" in the header flush left using all capital letters. The running head is a shortened version of your paper's title and cannot exceed 50 characters including spacing and punctuation.
The first page must have "Running head:***the shortened title), but subsequent pages just show the shortened title. To make it so that you can have different text in the header of each page, go to the Insert/Headers section of Microsoft Word and be sure to select the checkbox under the Header Tools that says "Different First Page".
If you check this, and if you also have a page/section break between pages one and two, then you should be able to have different text in the header of your first page than in the header on your subsequent pages.
