<br>
I second Reinhard's statements.<br>
However, I think maybe I can help you here straight away.<br>
<br>
I tried to typeset a test document with the data you provided. It
seemingly ran without problems, but no citations were inserted.
After closer inspection of the log output, it turned out that
BibTeX simply hasn't found the alphadin style and hence produced
no output (with printing a message, but without stopping the whole
process). Are you sure you have that style file installed (in
TeXlive, its part of the din1505 package) in a place where BibTeX
can find it? Can you run BibTeX alone to see if it produces any
errors or warnings? And have you run LaTeX often enough to resolve
all cross-references (sometimes it takes up to 3 runs)?<br>
<br>

PS: Once the file was installed, natbib complained that it was
incompatible with the author-year style. "
<meta name="qrichtext" content="1">
\setcitestyle{numbers}" resolved that.
