Currently my citations are like:
"blah blah (1) blah blah blah (2-6) blah blah blah blah (7,8)"
But I need that "(7,8)" to be "(7-8)". I'm using abntex2cite package, which automatically made the citations that way. Note that with multiple citation (more than 2) it already is the way I need. The problem is with exactly 2 references.
I tried using
\usepackage[labelsep=endash]{abntex2cite} but it didn't work (actually the error message says "Option clash for package abntex2cite"). Any suggestions?
Thank you!
abntex2citecitation management package?
