BibTeX, biblatex and biber ⇒ [?] error
[?] error
I have used a reference multiple times in my document. The first instance that I cited it, the reference worked fine. All following instances gives the [?] error. The citation key is correct, as the first instance that it was used the reference worked fine.
Does anyone know where I am going wrong?
Thanks
James

Take a look at the compiler log (*.log) and the BibTeX log (*.blg) and check them for warnings and error messages.
