Header/Footer inserts

I am trying to add a page number series on the bottom of the pages and alternating headers at the top, odd and even pages, and to begin these on the third page of my document. I cannot get it to do this. The page numbering shanges when I try to add the alterning header, and none of it will begin on the third page, even using a page break. How can I do all this?

Hello and welcome to the forums.
It would probably help if we knew which software you were using and having this problem with. If it is Word 2010 have a look at these two references.
Add or remove headers, footers, and page numbers - Word - Microsoft Office scroll down to "Add different headers and Footers or Page Number on Odd and Even Pages.
Get control of page numbers, headers, and footers - Word - Microsoft Office short class/tutorial that may help.
