LaTeX problem with figures


This is driving me slightly crazy. I have only been using LaTeX for a little while, but I have come across a problem. I have figures and equations in my document and they label differently. Basically, this is the problem:
I write something like this:


normal preamble...
\section{I have a problem}

Here is an equation. It is equation \ref{eq:einstein}

\begin{equation}
E=mc^{2}
\label{eq:einstein}
\end{equation}

Now here is a figure. I like to call it figure \ref{fig:albert}

\begin{figure}
\includegraphics[height=45mm]{einstein.eps}
\caption{A picture of Einstein}
\label{fig:albert}
\end{figure}
rest of document.

=============================
=============================
Now this should be fine, but what I get is something like this:

2.1 I have a problem
Here is an equation. It is equation 1

E=mc2 (1)

Now here is a figure. I like to call it figure 2.1

==========
||||||||||
||||||||||
|||pic||||
||||||||||
||||||||||
==========

Figure 1: A picture of Einstein

rest of document.

===========================
===========================
Now, although the figure is captioned correctly as "Figure 1: ~~~~~", when it is referenced it is appearing as "figure 2.1", or whatever the section number is. If I have more than one figure in a section, they are all referenced with the same number (the section number). As in the above example, equations work fine, but tables behave the same way as figures.
I thought I was doing this the right way, I've found loads of sites on the internet that say it should be done like this, but I just can't get it to work.
Any help would be most appreciated.

LyX

You may want to look at LyX, a WYSIWYM front end for LaTeX...works very nicely. One you have inserted your equations and figures the way you like them, you can export it to LaTeX code, and see how it needed to be entered in the markup language.

Thanks, but I primarily use LaTeX at university, where I don't have the power to install other software. Do you use LyX at all? If you have created any documents with figures in, I would be grateful if you could post the code for one. I'm pretty sure I'm doing it right, but obviously not.

example figure

I can't post attachements here, so you can't see what the output looks like, but here is the preamble and figure insertion commands I used. I think it turned out nicely. The figure is embedded within the text.. I have just included whtat I think are relative snippets.

%% LyX 1.3 created this file. For more info, see http://www.lyx.org/.
%% Do not edit unless you really know what you are doing.
\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{graphicx}

\makeatletter

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LyX specific LaTeX commands.
%% Bold symbol macro for standard LaTeX users
\newcommand{\boldsymbol}[1]{\mbox{\boldmath $#1$}}


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% User specified LaTeX commands.
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{geometry}
\geometry{verbose,tmargin=2.54cm,bmargin=2.54cm,lmargin=2.54cm,rmargin=2.54cm}
\usepackage{babel}
\usepackage{graphics}
\usepackage{setspace}
\usepackage{indentfirst}

\doublespacing

\makeatletter

\usepackage{babel}
\makeatother
\begin{document}


\noindent \begin{flushleft}where $\chi$ denotes distorted waves. \end{flushleft}

Equation (\ref{10}) refers to four different vectors: $\vec{r}_{n}$,
$\vec{r}_{p}$, and $\vec{r}_{d}$ and $\vec{r}_{pn}=\mid\vec{r}_{p}-\vec{r}_{n}\mid$.
The geometry of the reaction is presented by Figure \ref{1} . It
can be seen that only two of the four vectors depicted are independent.
The vectors $\vec{r}_{d}$ and $\vec{r}_{p}$ are associated with
the distorted waves corresponding to the incident and scattered particles.
The vector $\vec{r}_{pn}$ is necessary to describe the internal deuteron
state. The vector directed from the target nucleus to the center of
mass of the deuteron system is denoted as $\vec{r}_{d}$, and the
vector directed from the proton to the neutron within the incident
deuteron system is denoted as $\vec{r}_{pn}$. If it is desired to
chose $\vec{r}_{d}$ and $\vec{r}_{pn}$ as the coordinates of integration,
the other coordinates can be expressed in terms of these.

\begin{figure*}
\begin{center}\includegraphics[%
width=1.0\textwidth]{figure1.eps}\end{center}


\caption{\label{1}Reaction Geometry}
\end{figure*}


\begin{flushleft}The equations of transformation in this case are
given by:\end{flushleft}


Hope this helps. It correctly refers to Figure 1 in both the labeling of the figure and inside the text discussing it. Oooops...nevermind...my referencing is not that good, and I have figure references actually pointing to equations later in the paper (I never label or refer to equation 1 explicitly, so that I can label the figure as 1 and refer to it...latex just gets the equation numbering right at the time its processed). Oh well, looks like I cludged things manually and referencing wasn't too important, just printing out the number correctly, which I would have to change if I inserted more figures, equations, or changed their order. Sorry....

Yes, that's great! I need to label my figures within the captioning environment. Thanks a bunch, I've solved the problem now.
