Including the bibliography doesn't work

Question

Good afternoon,

I am a new to LaTeX and currently I am writing on my thesis, but I got problems on including my bibliography which is implemented as a .bib file. Probably I should add that there are no errors. I use: TeXworks and Jabref (for creating the .bib file)

Overview of what doesn't work:

• Citations in text with correct numerations (i.e. [1])
• Attachment of a bibliography section at the end of the document with corresponding entry in the content list

---

For example: sources.bib

@Book{Schroeder2000, title = {Elektrische Antriebe - Grundlagen}, publisher = {Springer Verlag}, year = {2000}, author = {D. Schroeder}, }

In my .tex file I want to include this .bib file. So I got something like that (There was a template given to me which contains the following lines, I tried to adjust them for my purposes but it didn't work):

\documentclass[a4paper,11pt]{memoir}

% packages
\usepackage{kantlipsum}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{csquotes}
% Language
\usepackage[english]{babel}
%\usepackage[ngerman]{babel}
\usepackage{helvet}
\usepackage[style=numeric, backend=biber, backref, sorting=none]{biblatex} % use backend=biber if available
\usepackage{graphicx}
\usepackage{color} % \definecolor{heatred}[RGB}{170,0,0}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{color}
\usepackage{siunitx} % \SI{15e3}{\kg}, \SI{0.2}{\m\per\s}, \si{\kWh}
\usepackage{mdwlist} % compact lists: \begin{enumerate*}, \begin{itemize*}
\usepackage{hyperref}
\usepackage{bm} % bold italic symbols in math mode
\usepackage{eurosym}
\usepackage{pdfpages}
\usepackage{tikz}

\addbibresource{sources.bib}

\begin{document}

% table of contents
\cleardoublepage
\tableofcontents

% content
%Include your introduction, etc.
\input{tex/01-intro}
\input{tex/02-main}
\input{tex/03-end}

% Bibliography
\clearpage
\phantomsection
\addcontentsline{toc}{chapter}{Bibliography}
\printbibliography

\end{document}

But when I cite in one of my tex documents (i.e. main.tex) it doesn't work.

This is how I cited in my .tex file:

And Mr. P stated that XYZ has happened \cite{Schroeder2000}

This is the output I get from the previous line:

And Mr. P stated that XYZ has happened [Schroeder2000]

Instead of:

And Mr. P stated that XYZ has happened [1]

---

Additionaly the last part:

% Bibliography
\clearpage
\phantomsection
\addcontentsline{toc}{chapter}{Bibliography}
\printbibliography

doesn't work, too. There is no bibliography section in my table of contents and there is no bibliography attached at the end of the document.

I am very sorry if the writing-style doesn't apply to the forum standards. It is my very first time here at this forum. Of course I searched for answered questions but I couldn't find any answers to my problem. I would like to thank you in advance for your help!
