How can I set different assessment values for each subquestion in multiple choice question? The assessment value option only accepts one number. I have seen 8+ years old examples that allowed that but I can't find that option now. I've also seen using the Expression Manager to sum the single values of each answer but what I need is to sum that to the total assessment score and not just get the single assessment score of each question.

Hi,
sum up your values by EM.
Different scores in a multiple question? No problem
Either:
sum(if(Q1_SQ001.NAOK=="Y",1,0),if(Q1_SQ002.NAOK=="Y",3,0),if(Q1_SQ003.NAOK=="Y",7,0),...

or
{sum(
intval(Q1_SQ001.NAOK=="Y") *1,
intval(Q1_SQ002.NAOK=="Y") *3,
intval(Q1_SQ003.NAOK=="Y") *7,
…
)}

Now you have the score of one multiple question with different weights.
You may save this score by setting this in a question of type equation (named i.e. "scoreQ1")

Later you may sum all your single scores {sum(soreQ1,scoreQ2,scoreQXXX,...)}

Generally Expression Manager is much more flexible and powerful than this "old" assessment feature.
