BibTeX, biblatex and biber ⇒ Problem with Citation

[Knallberto]

Hello,

I am rather new to Latex and Bibtex and trying to create my first document. I habe a *.bib file including two references. When I cite the second one it works perfectly fine, but when I put in the first one (in the same place) I get an error message

Citation `frid2019' on page \thepage undefined').

I am using \bibliographystyle{abbrv}
Here is the content of my bib file:

Code: Select all

@article{frid2019,
  title = {Accessible Digital Musical Instruments—A Review of Musical Interfaces in Inclusive Music Practice},
  author = {Frid, Emma},
  journal = {Multimodal Technologies and Interaction},
  volume = {3},
  number = {57},
  pages = {20},
  year = {2019},
  publisher = {Multidisciplinary Digital Publishing Institute}
}

@inproceedings{ablatherwick2017,
  title = {Design Considerations for Instruments for Users with Complex Needs in SEN Settings},
  author = {Blatherwick, Asha and Woodbury, Luke and Davis, Tom},
  booktitle = {Proceedings of the International Conference on New Interfaces for Musical Expression},
  address = {Copenhagen, Denmark},
  publisher = {Aalborg University Copenhagen},
  url = {http://www.nime.org/proceedings/2017/nime2017_paper0040.pdf},
  year = {2017},
  pages = {216--221}
}

What am I doing wrong?

Can you provide a minimal working example? Just seeing the bib entries isn't really that helpful.

Welcome to the forum!

Yes, some real code would be good to see, to check what happens. You can also post the .blg log file here, as attachment to a post. The attachment link is below the text edit field, when writing a post.

Thanks for your answers. I fixed the problem: It was about the UTF-8 compatibility. There was a hyphen in the online bib tex source (the one in the first bibtex entry) that was not supported, I just put in a 'normal' one and now it is working.
