Hi I followed the steps indicated under :
http://wiki.lyx.org/Examples/AcmSigplan I installed / reconfigured LyX and can open my article in the new ACM class; fine. The problem I encounter is when I include citations. I run into errors; here is an example of the error messages I get for each citation : ------ "Use of [EMAIL PROTECTED] doesn't match its definition. of Todd and Latham \cite{ ToddLathamEvoArt} and on the other hand, If you say, e.g., `\def\a1{...}', then you must always put `1' after `\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it." --------- I had no such problem when using the plain article class. Any idea what the above means? I am running LyX 1.3.7 under Ubuntu. Regards, Frederic -- Prof. Frederic Fol Leymarie Computing Dept., Goldsmiths College http://www.doc.gold.ac.uk/~ffl/ Tel: +44 (0)20 7078 5052
