I'm writing an article for a Springer journal and am trying to generate a Bibtex bibliography using the "spbasic.bst" style, which I have installed (correctly, it seems, as it can be found by LyX.
However, I get (?)s instead of citations when I compile and LyX does not produce a reference list. What could be wrong? It works perfectly if I use a different citation style, such as apalike.
Let me know if you need any code.
It's getting urgent, the article is finished and I want to submit, but I just can't get the citations right

Thank you!
