Hi all,


Many thanks in advance for your help


I´ve created a quiz with a multiple choice question.


A1 "Which of the following statistical methods are multivariate?"

SQ001 Cluster analysis

SQ002 Variance

SQ003 Cross-tabulation

SQ004 Multiple regression


The question is answered correctly if (only) question answers "SQ001 Cluster analysis" and "SQ004 Multiple regression" are selected.


After having answered this question, the participant should be able to see if his answer was right or wrong.

I found this solution in the forum: ( I already adjusted the variable names of the question)

{if(A1_SQ001.NAOK == "Y" and A1_SQ002.NAOK == "" and A1_SQ003.NAOK == "" and A1_SQ004.NAOK == "Y"),("You chose this answer correctly.","You chose this answer incorrectly")}


Unfortuntaley it´s not working (no text is shown at all after having answered the question).

In the question summary, the "if " of the function is marked red and the following error message is shown:

"Function does not support 1 arguments Function supports this many arguments, where -1= unlimited : 2,3; Not a valid expression; Conditional processing; if (test, result_if_true[,result_if_false=""])

I´m a limesurvey newbie and didn´t succeed at finding the error.

Do you know how to adjust the code so that it´s working?


Thanks a lot! I attached a picture of the question summary.


Kind regards

Hi Elissa,

I´m sorry for my late response. Unfortunately I got ill and just found the time to have a look at you solution.

Thanks a lot for your answer! Your solution is working for me, too.

Do you know if there is any possibility to show the text "You chose this answer correctly." in green and "You chose this answer incorrectly" in red colour?

If yes, could you please show how the code needs to be adjusted in order to show the different text colours?

Many thanks in advance

Hi,
I'm not sure if you can use html code within an expression so my solution is: Regards

You can

With this restriction : manual.limesurvey.org/Expression_Manager#XSS_security

And just remind to use different quote

But for such purpose, i think usage of boostrap class can be better : getbootstrap.com/docs/3.3/css/#helper-classes-colors or getbootstrap.com/docs/3.3/components/#alerts

Thanks a lot for your support! It´s working now with this code.

{if(!is_empty(A1_SQ001.NAOK) and is_empty(A1_SQ002.NAOK) and is_empty(A1_SQ003.NAOK) and !is_empty(A1_SQ004.NAOK),"<font color='green'>You chose this answer correctly</font>","<font color='red'>You chose this answer incorrectly</strong> ")}

@DenisChenu Thanks a lot for your link, this seems to be very helpful for future problems.

Just an example:

Hi Tammo,

thanks a lot for this example. Is there any way to have a look at the syntax so that I can see how the evaluation summary on the last page of the survey is created?



Many thanks in advance

Hi Maria,

All material form that book and the website gapminder.org is open for sharing.
