I am using Jabref as a bib-file and push the ref via "lyx" in Jabrefs menu into the document. Jabref allows also to check for the coding ( file>database properties>encoding>ISO8859_1).

I find it faster to mark parts which you have to do anyway if you put it in a comment field, use ctr x, try the rest, if ok, paste it back with ctr v, try the other half etc until the error has been pinned down.

Re: ! Missing $ inserted.
Thanks for your comments. Just to update you, the problem was due to incompatible encoding in BibTeX. I imported some citations with accented characters in the author names - these failed to show in the reference database. When I over-rode the encoding by manually inserting the characters, the problem went away. Took me several days to work out!

Re: ! Missing $ inserted.
Uups, the last one went off too early. I also had these kind of errors and often found them caused by bibtex-related problems, mostly special characters. Instead of actually splitting your document in search for the error I turn document parts into comments, which is easily undoable.

Re: ! Missing $ inserted.
To locate the source of such problems, I export the file to latex and manually compile it to latex in a terminal (or command window in Windows). The compilation will give you a line number. You can open the latex file in a simple text editor and go to the line to have an idea of the part of the document that poses problem. -- Murat Yildizoglu yi...@u-bordeaux4.fr Le 6 janv. 2012 à 03:07, "David L.

Hi Gerry, Because I know very little of LaTeX, the underlying technology of LyX, the way I fix these type of problems is divide and conquer. First I back up my file for safe keeping. Then I split it roughly in half, and see if the symptom remains. If it does, I split it in half again. If it's still there, I split it in half again, etc. Of course, sometimes the symptom goes away when I take material away, so when it goes away, I put back half the material I last took away. Keep half-splitting it and pretty soon you'll get it down to a tiny document that exhibits the problem, and the root cause becomes obvious. This works for just about any situation where LyX fails to compile to PDF etc. Hope this helps.

Re: missing $ inserted : what does that mean?
Dear All, Thanks for your comments! I used James' suggestion and deleted each section. My document is more than 120 pages, so I spent a good few hours fixing the problem. Today I found Paul's comment which was "right on the money"! This was exactly the cause. For some reason, two citations in two separate footnotes went crazy. I can't even see why in the bibtex file, but when I re-entered them as new citations in the bibtex database, it works. Quite annoying. :-) Thanks all for your help, Erez On Fri, Oct 31, 2008 at 6:29 PM, Paul A.

Re: missing $ inserted : what does that mean?
That's a LaTeX error. Something is odd with the way you're putting in your equations. I often find it useful to export the LyX document as LaTeX and then see where the error comes from there. You can also click on the error message in list and see the line in the original LyX document that causes the problem. Either way should give you some insight into the problem.

Re: missing $ inserted : what does that mean?
I sometimes have this problem due to what is likely a bug in LyX. Try the following: segment your document into several documents and see which one(s) fail. Continue removing until you find the offending part(s). Then if you also look at the LaTeX source code you can sometimes find the problem. Ususally for me it is an "extra" space (LyX typically eliminates those, and if it doesn't for some reason, things break).
