[support] correct use of bib

hello i am using the biblio modukle together with footnotes. while the fn /fn tag works and creates an automatically numbered list of footnotes, I cannot get the bib /bib tag to work. either it says citekey not found or, after I put as citekey the nodeID in the configuration it just outputs the bodeID nr between brackets. what am I supposed to put between bib and /bib and which other configuratuions do I have to consider? thanks in advance Armin
