Unexplained error

I faced this kind of error before. What I mean by unexplained is that the location of error shown by Lyx does not contain any error. Sometime it is just one word without any L^aT_eX command at the location. By the way, I should mention for the benefit of newcomer, Lyx will highlight the supposedly error location. In this case of error, the highlight is at random location and you can explain what is the actual error. The unexplained error usually occurs, at least I experienced it, once I include a citation. I use BibTeX to generate reference list. The .bib file is linked to the Lyx file and once a citation is included, BibTeX will run the process of creating the list. Error will occur if the bib database contains error, usually it has an illegal character. You know, citation info can be exported directly from publisher’s webpage or even from Google Scholar page. The auto export function is the culprit of the error. Some of the article title or even the name of authors can have illegal characters. Most of it is characters like % and &, which is the command character in L^aT_eX. So, the errors can be overcomed by making sure that the bib database doesn’t have any of this illegal characters. That will it for now. See you soon!
