Think of multiple choice question with three answers.

Then a equation question with this content:
When you check all three answers the result of the equation is (1*5)+(1*10)+(1*15)=30.
This is displayed correctly but Limesurvey saves NAN in the results.

This behavior might be as intended.But how to save the result of such calculation inside the results?
LS Version 2.06+ Build 150731and Version 2.05+ Build 150508 both show the same behavior.

Just a demo survey with checkbox and radiobutton question. Values from the single choice question are saved, when using multiplechoice items 0 or NAN are saved in the results. Perhaps I'm too dumb and too blind.

It may be because check_SQ001.NAOK == "Y" returns true or false, not a number. Try using equation questions to define those variables.

Something like this in the equation:

Thanks for your time.
When you run the survey the values are all calculated fine. It is the saving in the results which won't work.

I have tried different things over 4 hours to find where I made a mistake. But every workaround (e.g. using count or if ) I could think of didn't changed the missing value in the results.

And Limesurvey itself is creating this relevance equation from the condition "checkbox 1 is ticked":
((check_1.NAOK == "Y"))

What a riddle.

Mhm. Tony. I tried it once again with the IF. This time it worked. I still wonder, why the value is shown correctly, but not saved. Thanks again for motivating me to try it once again with the IF concept.

That might be worthy of a bug report.
