==================
Basically I need take answer code that I set as numerical value of certain sets of answer (version A and version . Then process them into scale weight.

Sorry english is not my first language so it might be confusing. Also I'm not really a programmer so if their is any video guide, it would be really helpful.

I am not really sure what you are trying to achieve.

You might need to explain it a little bit better, maybe a sketch / image can help to explain?

Version 3.27.18+210921

Your installation is 1,5 years old and hasn't received any updates, bug fixes and security patches for the same time. You should consider doing an update.

So I need to do a questionnaire where I would ask "Which is more important, A or B?"

- A is more important
- B is more important
- They have the same importance (valued as 1)

If they say "A is more important", they would go to question 1A "How important is A compared to B?"

- slightly more important (valued as 2)
- more important (valued as 3)
-significantly more important (valued as 4)(but the scale would go up to 9)

But if they say B is more important, they would go to question 1B.

First, can you tally up the value of all question A separately and question B separately? I see using the assessment tools you can tally up per question group but I don't think I can work with this since everything would be in the same group.

Also can you set the assessment value as minus? Because then I think I can work around that by having the scale from -9 to 9 rather than 1 to 9 but going both way

like this
Criteria A     -9 -8 -7.....0 +7 +8 +9        Criteria B
instead of
Criteria A    +9 +8 +7...... +7 +8 +9       Criteria B

Instead of assessments, use ExpressionScript to generate your scores in equation type questions.
