Hi dear community, i I´m just using this : "Question validation equation : unique(self) and count(self)==max(self)" provided by shnoulle on demonstration.sondages.pro/714997# in order to have an Alternate Ranking question.

I have LimeSurvey Versión 2.06+ Build 151126 and this solution works ok but the same solution doesn´t work on LimeSurvey Versión 3.15.1+181017.

I´ve noticed that the only thing that doesn't works is the function max().

i´m attaching the lss file in orther to test my solution.

Thanks In advanced, i´ll really appreciate your help.

Maybe you can test downgrading to github.com/LimeSurvey/LimeSurvey/releases/tag/3.14.4%2B180810

But without ANY guarantee …
