Text Formatting ⇒ Question about \cite

[pixinot]

When using \cite{link1, link2, link3 etc} in my article, the output is [1,2,3], although it should be [1-3]. Can you tell me what is wrong in my code?
I use bibtex, and there is a sample of my code:

Code: Select all

Please try to provide a minimal working example and mark your code as code.

The natbib package offers other options besides numbers, which are listed and described in its manual, e.g. those to compress multiple numerical citations if possible.

You need to add the "sort&compress" option to natbib.
