Hi,
here
www.limesurvey.org/manual/ExpressionScri...mplemented_functions
you find the function "countif"
This gives you the number of answers to each item a,b,c,...
With a nested "IF-statement" decide what he likes
{if(countif("a",Q1.NAOK,Q2.NAOK,...)>2,"rock",if(countif("b",Q1.NAOK,Q2.NAOK,...)>2,"disco",if(...
What happens if there is a 3:3 distribution like "a,a,b,a,b,b"?
