# Adding footnote will move to the next section into a new page

I am trying to create a page looks like this in one page:

Section 1

Blablabla(footnote here)

Section 2
Blablabla
----------------
Details in the footnote....


However, when I use footnote, the latex gives a printout like this

Section 1

Blablabla(footnote here)
------------------------
Details in the footnote.

------ Big empty space here ----

In the next page
Section 2


Any one would know how to adjust footnote?

Thanks very much!

Example

%&pdflatex
\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{graphicx,psfrag,epsf}
\usepackage{enumerate}
\usepackage{natbib}
\usepackage{url} % not crucial - just used below for the URL
\newcommand{\blind}{1}

% DON'T change margins - should be 1 inch all around.

\begin{document}

%\bibliographystyle{natbib}

\def\spacingset#1{\renewcommand{\baselinestretch}%
{#1}\small\normalsize} \spacingset{1}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%    %%%

\if1\blind
{
\title{Title}
\author{Author}
\maketitle
} \fi

\bigskip
\begin{abstract}
Abstract
\end{abstract}

\newpage
\spacingset{1.45} % DON'T change the spacing!
% --------------------------------------------------- %
\section{Section 1}
\label{sec:intro}

\Section{Section 2}

\end{document}

• Welcome! This is nowhere near enough information to help you. This is not the default behaviour unless section 2 starts with a large box. Please post a Minimal Working Example i.e. code for a minimal but complete document which we can copy-paste-compile to reproduce the problem. – cfr Jul 9 '16 at 22:48
• I have update an example in the question. Thank you for helping out! – Po Ning Jul 9 '16 at 23:03
• Did you check your example compiles? Because I bet it doesn't. – cfr Jul 9 '16 at 23:08
• When I correct your code, I get a 2 page document. Abstract on page 1. Section 1, footnote and section 2 on page 2. – cfr Jul 9 '16 at 23:11
• Sorry, I forget to check my example compile. However, thanks to your correction. Yes, this is the result i got. However, I want the section 2 is followed with section 1 in the same page. – Po Ning Jul 9 '16 at 23:21
