This equation is used further down the survey, but it looks like it causes prefilling answers.

The double "==" cannot be changed, since changing to single "=" generates a syntax error.

Hi,

You must not use = :
TIP0 : Relevance equation: ((VQ1_SQ001.NAOK="Y") AND (VQ1_SQ002.NAOK="Y")) You have to replace with
((VQ1_SQ001.NAOK=="Y") AND (VQ1_SQ002.NAOK=="Y"))

Same in VQadres and surely some other.
