My problem is that I am trying to merge multiple occurances of a footcite on a page. It is the same situation as discribed in: https://tex.stackexchange.com/questions/126981/merging-duplicate-footcites. Unfortnatly the example does not work for me, which may be caused through the use of the following header:

  • Your MWE does not include the \superfootcite code from the linked answer.

  • As I have stated before: it did not work, therefore i did not include it.

Using the code from the linked question does work:

Text sample

Foot sample

Note that I use \superfootcite rather than \footcite. Also I changed your \bibliography command to \addbibresource.
