I hope someone can help me with the following problem.
When I try and compile a file with a reference in it (using Texmaker), I get the error message Undefined control sequence.
I subsequently went into my BibTeX file and corrected the error which was a missing bracket. However when I then try and compile the file (latex, bibtex, latex, latex) or quick build in Texmaker the same error message comes up.
The weird part is that even when I change the reference to something else, the same error message specific to this reference comes up.
What has gone wrong? I think it might be related to the natbib package as I have had problems with it before.
A brief example can be provided should someone need it.
.auxfile? This should be done when mysterious errors such as this one pop up. – egreg Oct 27 '11 at 13:09
