I am going to insert my references in my thesis, and I have tried to use bibtex. The problem is that I only get a question mark in the document, instead of the reference number. I know there are similar questions about this elsewhere, but I didn't manage to solve the problem.

My bibtex-file is: 

  @article{miller1993introduction,
  title={An introduction to the fractional calculus and fractional differential equations},
  author={Miller, Kenneth S and Ross, Bertram},
  year={1993},
  publisher={Wiley-Interscience}
}

@article{barton1974engineering,
  title={Engineering classification of rock masses for the design of tunnel support},
  author={Barton, Nicholas and Lien, Reidar and Lunde, J},
  journal={Rock mechanics},
  volume={6},
  number={4},
  pages={189--236},
  year={1974},
  publisher={Springer}
}

which I have called bibfile.bib

The latex-file is:

    \begin{abstract}
    \normalsize

    %%missing


      \end{abstract}

    \bibliographystyle{apacite}
    \bibliography{bibfile}
        \end{document}

My question is therefore what I have done wrong since I get question marks in the latex document?
