package keyval error: current slide undefined [closed]

I'm trying to prepare a presentation using latex but it gives an error:

"package keyval error: current slide undefined. See the keyval package documentation for explanation.Type H for immediate help. ... l.50 \end{frame} [return] Try typing to proceed. If that doesn't work, type X to quit."

This is how my presentation latex code looks like:

\documentclass{beamer}
\usepackage{beamerthemesplit}

\usetheme{Warsaw}
\usecolortheme{default}

\usepackage{pgf,algorithm,algorithmic,amsbsy,amsmath,amssymb,epsfig,bbm,mathrsfs,mathdots, subfigure}
\usepackage{graphicx}

\newcommand{\beqn}{\begin{eqnarray}}
\newcommand{\eeqn}{\end{eqnarray}}
\newcommand{\ba}{\begin{array}}
\newcommand{\ea}{\end{array}}

\title{On Cooperative }
\author{K. }
\institute{Department \\
University \\
}

\date{  \\ {\today}}

\setbeamertemplate{footline}{\hfill

\begin{document}

\AtBeginSection{}

\frame{\titlepage}

\begin{frame}[allowframebreaks]{Outline}
\fontsize{9}{4}\selectfont{}
\tableofcontents[currentslide]
\end{frame}


Any help, pls

• Remove [currentslide] from \tableofcontents. – Sigur Feb 7 '15 at 23:28
• \fontsize{9}{4}\selectfont{} specifies text that is in a 9pt font on lines that are 4pt apart, do you intend that? (and don't load epsfig:-) – David Carlisle Feb 7 '15 at 23:38
• Unconnected to the question, but that attempt to make 'shortcuts' for the align environment will fail. Use the proper LaTeX environment syntax, making use of your editors automation features as appropriate. – Joseph Wright Feb 8 '15 at 9:20
