Bibtex's inproceedings gives me an error.

entries:

@inproceedings{elgamal:84,
Author = {T. ElGamal},
Crossref = {crypto84},
Pages = {10--18},
Title = {{A Public Key Cryptosystem and a Signature Scheme Based on Discrete Logarithms}}}
@proceedings{crypto84,
Booktitle = {{Proceedings of Crypto '84}},
Editor = {G. R. Blakley and D. Chaum},
Publisher = pub-springer,
Series = j-lncs,
Title = {{Advances in Cryptology}},
Volume = {196},
Year = {1985}}
These worked in the past and should be ok.

The error is:
