==================
(Write here your question/remark) Hi, I'm new to LimeSurvey.
I'm struggling to see how I could implement a rule where in a vocabulary test, if a participant gets 6 consecutive questions wrong, that section of the survey is ended.
It's important, because, otherwise the participants  (children) will have to try to answer too many questions that are too hard for them and they will tire.
There are already conditions set up for the vocabulary test where the start point varies according to age.
Any advice gratefully received- even if it's confirmation that it can't be done.
 

Can you provide a sample survey (.lss export)?

Please, send a lss export that we see the structure

Oh, Tony beat me.

 Thank you for the quick response!

Is this right?

Thank you both for your speedy replies!

No. You need to attach the file. you can't just copy it into the editor.

There is no file attached, only the file name written as text.

Thank you- all very new to me. Ive just tried again.

Hi,
only 6 consecutive questions, 5 consecutive wrong answers, then one correct answer, again 5 wrong answers is fine?

I am thinking about a formula with different assessment values (0= correct, 1 = wrong)
So we have a question called "counter"
after each question there is an equation like
{counter=sum(counter,QCode,valueNAOK)*QCode.valueNAOK}
So, if the answer is wrong, the counter is raised by 1 and multiplied by 1
But if the answer ist correct, everything is multiplied by 0 and the counter is 0.

The questions get a relevance equation beside the age:  "counter<6"
This is a very rough idea. I will try it later.

Some other words:
Please revise your question types. To display a text (like "Let's start", etc.) use a question of type "text display", not "short text"
And better to use Expression Manager to enter the relevance equation than the "Condition Builder".
Just type AgeYears<=13 into the "relevance equation" field.

And I saw that your three questions regarding age are not validated.
With a birthdate of 2015, I can enter an agegroup of 11 and an Age of 13.

This - above - idea works.
But you will need two more equations for each of your test questions.

Here is a different idea:
Create in the first group a (hidden) question of type "short text" (counter). This will be the container for the results.
Now, after each test question add a (hidden) question of type "equation" with this
{counter=join('#',V11.valueNAOK,V12.valueNAOK,V13.valueNAOK,V14.valueNAOK,V21.valueNAOK,V22.valueNAOK,V23.valueNAOK,V24.valueNAOK,V31.valueNAOK,V32.valueNAOK,V33.valueNAOK,V34.valueNAOK,'#')}

Here only four questions of each age group.

In the question "counter" you join the assessment values of all questions.
Answering the questions "wrong", "right", "right", "wrong", "wrong", "wrong" will give a result like
#011000#

In my small example I leave the test after three consecutive "wrongs"
Meaning: If the above string #011000# contains "000" there are three consecutive "wrongs".

Now you can set the relevance equation of the questions to
(AgeYear le 13 AND strpos(counter,"000")==0)
resp.
(AgeYear le 15 AND strpos(counter,"000")==0)
(AgeYear le 17 AND strpos(counter,"000")==0)

Proceed, as long there is no "000"
About "strpos" read the manual about "implemented functions"
[url] www.limesurvey.org/manual/ExpressionScri...mplemented_functions [/url]

Here a sample survey.
 

My other idea I will show later

Joffm

And here a different solution
Remember: Assessment values are reversed, right = 0, wrong = 1

 

But to be honest: I am not so happy with these solutions.
You may change your approach, saying
"all wrongs in this series of first section", age <14
"5 wrongs in this series of second section", age<16
Then split the third section into 6 parts, after each
"5 wrongs in this part".
This would be much easier to calculate.

Thank you very much indeed for your time and thoughts on this.
Apologies for the delay in replying- it has taken me a while to get my head around this.
I went with your second option because I understood it the best (!) and have added all the additional 90 equation questions plus the relevance equations for the 90 vocab questions. And it still doesn't work!
What did I do wrong?

I'll attach my revised survey.

 

Revised survey attached. Many thanks.
