I want to simply add the results of a set of questions within another question (which will be hidden) so it will show up in the database. So if I have Q1, Q2, Q3, Q4, and Q5 which are all Question Type: List (radio) and the resulting answers will show numbers 1-5 for each of the answers selected I would like Field T1 (Question Type: Equation) to include the sum of those numbers. I tried to input a couple of different options like Q1+Q2+Q3+Q4+Q5 or {SUM(Q1,Q2,Q3,Q4,Q5)} into the Question but the first one one sent me all the numbers not the totals and the second one has an error in the logic file which I have attached. I assume this equation goes in the Question field not in the Equation field but I have tried it in both places.

I would also like to do this for the average of these questions. So if I have Q1, Q2, Q3, Q4, and Q5 which are all Question Type: List (radio) and the resulting answers will show numbers 1-5 for each of the answers selected I would like Field A1 (Question Type: Equation) to include the average of those numbers. I assume that if I get the correct syntax above that the average syntax might be something like {SUM(Q1,Q2,Q3,Q4,Q5) / COUNT(Q1,Q2,Q3,Q4,Q5)} or something like that since I do not see an average function in EM.

I searched through the Forum but did not find anyone who seemed to have addressed this question. I would appreciate any direction on what I am missing in my syntax or where I am placing the syntax.

sum !== SUM :).

Changing to a lower case of SUM {sum(Q1,Q2,Q3,Q4,Q5)} passed the logic check however the result is 0 (see Responses attached)

If I simply do this Q1+Q2+Q3+Q4+Q5 it will give a result something like this 3+3+5+2+2 (based on the Codes and Answers you see attached).

What is causing the 0 in this question field after running through an assessment?

Try:

Code:
{sum(intval(Q1), intval(Q2), intval(Q3), intval(Q4), intval(Q5))}

Hi,
instead of talking too much without exact knowledge, please send us your sample *.lss.
I just created your design, 5 radio questions with codes 1-5, equation question {sum(Q1,Q2,Q3,Q4,Q5)}
And got the correct result.

Version 3.15.5+181115

Can you create a new survey, with only this 5 questions and check again …

If some question have relevance, you must use .NAOK
