# Trying to make citation with parenthesis but get only square brackets

I want to use the following citation style

(AuthorName, Year)

I tried to do this by using the following commands

\usepackage{natbib}
...
\setcitestyle{round}
\bibliographystyle{plainnat}
\bibliography{references}


but the results is:

[AuthorName, Year]

Because I am not that comfortable with latex, I am also adding the other packages I am using, just to make sure I am not using something that comes in conflict with the natbib package

\usepackage{placeins}
\usepackage{amsmath}
\usepackage{subcaption}
\usepackage{soul}
\usepackage{float}
\usepackage{amssymb} % Fancy letter package
\usepackage{mathrsfs} % Fancy letter package
\usepackage{caption}
\usepackage[toc,page]{appendix}


Update 1:

I forgot to mention that I am using overleaf.com for my document.

• The packages you show should all be harmless and should not influence the brackets around citations, so there must be something else going on. Can you please prepare a full example document that reproduces the issue? (An MWE: tex.meta.stackexchange.com/q/228/35864) – moewe Nov 29 '19 at 15:25
• Do you have \setcitestyle{round} in the document body? I can't quite tell, but the code snippet suggests you do. Try moving it into the preamble (i.e. before \begin{document}). – moewe Nov 29 '19 at 15:27
• @moewe you are right. That fixed it. I wrote your suggestion as an answer, for future readers. But if you write the answer your self, I will accept it as the correct and delete my answer. :) – Dimitris Pantelis Nov 29 '19 at 16:22
• Nah, it's fine. Just remember to accept your answer (when you can, I think there is a waiting time)? – moewe Nov 29 '19 at 16:25
• ... Deleting large parts of text/code is easy with the binary search technique (delete half of the code, see if the error persists, if so, repeat; if not add the deleted half back in and delete the other half, repeat). With binary search you only need $O(\log_2 n)$ steps to reduce $n$ lines of code (so about 10 steps for 1000 lines of code). – moewe Nov 29 '19 at 16:34

I had \setcitestyle{round} inside of \begin{document} ... \end{document}. After moving it before \begin{document}, it worked properly.
