Bibtex wont work [duplicate]

Question

Please help! I am completely at a loss. Despite me copying commands directly from websites, my Latex document refuses to typeset either my citation or bibliography entry. Below is my tex...

\documentclass[12pt]{amsart}

\usepackage{geometry}

\usepackage{qtree}

\usepackage{natbib}

\usepackage{cite}

\geometry{a4paper} 

\title{Nominals of Modern Greek (Abstract)}



\begin{document}

Important to note, is that if their are no other items in the lexical phrase, 
the D must appear to the left side of N i.e. *\textit{podia ta}, citet{MG21}.

\bibliographystyle{te}

\bibliography{Syn3 Ref.bib}

\end{document}

Here is my bibliography entry saved under "Syn3 Ref..."

 @book{MG21,

   auTHor = {Brian D. Joseph and Irene Philippaki-Warburton},

   YEAR = {1987},

   Title = {Modern Greek},
