I'm trying to run the code below but I receive this error: "Option clash for hyperref" Please guide me what should I do. Any help appreciated. Here is the code:
hyperref is loaded twice:
Just remove the first loading without options.
A package can be given several times in LaTeX, however, the options of the calls after the first
\usepackage must be a subset of the options present in the first
\usepackage call, because LaTeX does not actually input the
.sty file more than one. (Otherwise each
\newcommand, ... would cause errors, if called more than once.)
