Hi Yuri,
it's seemt have typo issue at this :

if (count($args) > 2) { 

must be i think :

if (count($arguments) > 2) { 

Just one question :
i have create a new custom formula, it's appear on sandbox, but not on AdvancedPack report (complex expression sample).
i have certainly a missing files somewhere or it's a choose for not have issue with users.

Regards
