I have created a survey to know lecturers performance and every student has to evaluate 3 lecturers.

Group1:
Q1: Lecturer A, B, C, D, E
Q2: Lecturer's performance (choosen one from above)

Group2:
Q3: Lecturer A, B, C, D, E (all lecturers will be displayed excluding the one chosen in Q1 via array filter)
Q4: Lecturer's performance (choosen one from a pool of four in Q3)

Group3:
Q5: Lecturer A, B, C, D, E (rest 3 lecturers will be displayed via array filter)
Q6: Lecturer's performance (choosen one from a pool of three in Q5)


Problem: I am facing problem in evaluating the performance of each lecturer, because sometime one lecturer is chosen in group 1 sometimes in group 2 and sometimes in group 3

Any suggestion will be highly appreciated as 25% of students have already evaluated and evaluation is becoming critical as some 60 students still have to fill it.

Thanks in advance.

group one
q1 = multiple choice (set to minimum 1 answer)
q2 = has the same answer codes as their corresponding multiple choice question. add the correct SIDXGIDXq1Id (ex. survey id is 12345, group id is 789, q1 question id is 10 so it would look like 12345X789X10)to the array filter option in q2 (advanced settings).

group two
q3 = multiple choice. add the correct SIDXGIDXq1Id to the array filter exclusion option. (set to minimum 1 answer)
q4 = has the same answer codes as their corresponding multiple choice question. add the correct SIDXGIDXq3Id to the array filter option in q4.


group three
q5 = multiple choice. add the correct SIDXGIDXq1Id and SIDXGIDXq3Id to the array filter exclusion option. Make sure you separate them with a semi colon. (set to minimum 1 answer)
q6 = has the same answer codes as their corresponding multiple choice question. add the correct SIDXGIDXq5Id to the array filter option in q6.

Every item that is being filtered must have the same answer code as the item filtering it.

Array filter exclusion will remove the item selected, array filter will only show the item selected.

You can only filter questions with a multiple choice question.

If you are not using multiple choice questions and you cant take the survey offline to add one, you will need to do this with javascript to hide the options/rows you don't want them to see. Be weary of mandatory logic if you end up hiding stuff though (ex, hide an array row, it will still be mandatory thus stopping people from proceeding)

Idea:
- Add 5 equation question type (one for each Lecturer)
- In the equation for lecturer A: put this equation: etc ...
- You get the good "Lecturer's performance" in each column for each Lecturer

You can not do it after survey is activated. You can deactivate survey and reactivate after and import old response table (or VV file).

After, maybe you can try www.limesurvey.org/en/extensions/68-recomputeexpression to update Equation question text for the first answers

Thank you Denis and Bigred, I will test it today.
