I don't think this has been answered before, but I am running into an 'error undefined' problem when trying to export to pdf. I have placed the \counterwithin{figure}{section} to the preamble and selected the AMS package as I should, I was able to get \numberwithin{equation}{section} to work that way. When I have it in the preamble it gives me the error, when I take it out it exports normally, but all my figures are numbered sequentially throughout.
Perhaps I am missing a file, and if so: what file is it and where do I put it so this works? If this is needed, I am running Ubuntu 8.04 and am using Lyx version 1.5.3 -- View this message in context: http://n2.nabble.com/Figure-Numbering-Error-tp2380764p2380764.html Sent from the LyX - Users mailing list archive at Nabble.com.
