# Page numbers in different positions on different pages

I'm having problems with the page numbers in my document. I'm using a template that my lecturer has given us all and haven't touched the page numbers but they appear in different places as you go through the document. It's at the bottom, centre of the page on the first page, and the numbers carry on from then on to be in the right hand top corner. I've tried to fix this myself but I can't seem to, however this is my first time using LaTeX. Any suggestions would be appreciated. Here is what I've got at the top of the document currently:

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,graphicx,hyperref,parskip,gensymb,fancyhdr}
\usepackage[cm]{fullpage}

\begin{document}


I also tried \pagenumbering{gobble} to get rid of them (which worked) and then \pagestyle{arabic} to bring them back- hoping they would all be in the same place but this didn't work. Preferably, I would like all of the numbers to be at the bottom of the page, in the centre. Thanks!

Edit:

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,graphicx,hyperref,parskip,gensymb,fancyhdr}
\usepackage[cm]{fullpage}

\begin{document}

\title{Modelling the Back End of a Bus}

\maketitle

\begin{abstract}
.....
\end{abstract}

\section{introduction}
....
\end{document}

Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Your example is not a MWE by the way ;-) –  Christian Hupfer May 11 '14 at 15:32
Use the fancyhdr package to get better control of the page layout for headers and footers. –  A.Ellett May 11 '14 at 15:38
@A.Ellet: The OP uses fancyhdr already, but not \pagestyle{fancy} –  Christian Hupfer May 11 '14 at 15:41
The described behaviour is the EXPECTED one. The first page of a chapter shouldn't have, generally, a running head. –  Przemysław Scherwentke May 11 '14 at 15:43

Thank you, that's great! –  Ella May 11 '14 at 16:58
@Ella Glad it helped. –  cfr May 11 '14 at 17:38

Use fancyhdr:

\documentclass{article}
\usepackage{fancyhdr}
\pagestyle{fancy}

@Ella You need to set all the positions \lhead{...}\chead{...}\rhead{...}\lfoot{...}\cfoot{....}\rfoot{...} where ... is whatever content you want to show up in that position. –  A.Ellett May 11 '14 at 15:51
Better yet, use \fancyhf{} to clear all the fields and then set the one you want. By the way, it's better to use \fancyhead[R]{\thepage} rather than \rhead{\thepage}: it's clearer and more easily manageable. –  egreg May 11 '14 at 20:38
