Hi, can I set it so that the participant must mark the correct answer, otherwise he will not move to the next question?



e.g. The grade value must be 1 to go to the next question

Please refer to the manual - question validation equation - www.limesurvey.org/manual/Question_type_...28em_validation_q.29

Ok, if I have List(radio),

code/value
AD1 / 1
AD2 / 0
AD3 / 0

and correct answer is code: AD1, value==1


How do I have to write logic?

xxxxxx- what should i consider there?
or otherwise?

Question validation equation:
((xxxxxx)==0)

Question validation tin(en):
{if(((xxxxxx)==0,",'Incorrect'}

Please help me! I will be grateful!

And what is the code of the question?
Let's assume "Q1".

So if the correct answer is AD1, your question validation is: "Q1==AD1",
and in the tip you might set an if-statement to show the FALSE state.
Like
{if(Q1==AD1,"","Your answer is not correct")}

I will be grateful!

Ok, send me a beer.

Joffm

I still have an error, undefined variable in the red square

probably I am describing something wrong



in code should i use id?

ok, I would send beer from Poland, but we have slops here

1. "A4" is a text, so it has to be surrounded by quotes.

And, sorry, I was a bit short, that I did not use quotes in Q1=="AD1"
Because I just wanted to show the structure.
