I have a BibTeX generated list of references that is doing one entry incorrectly. As sen in the attached picture there is a period being placed after the question mark. I need to remove this period but am I having difficulty doing so. I found this solution
http://tex.stackexchange.com/questions/181130/remove-question-mark-following-period-for-reference-title-in-pdf-using-vancouve I tried to implement it by adding the \killpunct after the question mark in my .bib file and then added \newcommand{\killpunct}[1]{} to my preamble. Upon compilation I get an error that there is a built in limit of 9 arguments. Searching around it seems like there are some fixes to overcome this limitation but nothing straightforward and all involve lots of programming in LaTeX, which I am not comfortable with. Is there any easy fix to remove the offending period? -- Steve Burnham
