Xelatex compiler still an issue on overleaf

[trecsim]

Setting custom font is somehow now working

\ifsetCustomFont % Set your custom font here and use 'customfont' in options. Leave empty to % load computer modern font (default LaTeX font). \RequirePackage{helvet} \usepackage{fontspec} % For use with XeLaTeX \setmainfont[ Path = Font/, Extension = .ttf, UprightFont = *-Regular, BoldFont = *-Bold, ItalicFont = *-Italic, BoldItalicFont = *-BoldItalic, ]{Verdana} % % load font from system font % \newfontfamily\libertinesystemfont{Linux Libertine O} \fi

if I remove the if condition it works fine, however. Any ideas as to why? I am adding the customfont attribute when I create my document.

Thanks
