So by adding various answers to this quota I reduced the chance to close this quota with every answer I added.

Holger, could you please add a hint at the docs, you are probably not the only one running into such a problem.

Thanks!

Hello,

You can set a quota to for each question, then it's an OR not a AND.

It's the best way for quota: then you can have AND and OR quota on the same survey.

Denis, can you help updating the manual as well? I think this information is missing there?!

There are already an example with 2 quota:
docs.limesurvey.org/quotas#Example_of_a_quota

You might have to conduct a survey where you want to limit it to 25 male and 30 female respondents. You could then define a quota with a limit of 25 for the answer "Male" from your gender question in the survey. Another quota for the answer "Female" with a limit of 30 could be added as well. This will give you a maximum of 25 males who will be able to complete the survey, and a maximum of 30 females who can complete the survey.

I will see if I find time to have a look at this next week. This week is just crazy here.

Maybe I can add a paragraph about "screenouts"/"zero quota".

Hi,

I notice that the initial problem of this topic had been solved a couple years back by assigning zero Quota. However I still have a question regarding screening out and would really appreciate any input.

Using zero Quota for screening out is a wonderful solution and works perfectly. However there are circumstances where Quota becomes not feasible, such as where the question types are not supported by Quota.

In my case, I have an array question (attached picture.png) where the allowed answers to go to the next questions are (Q_Question2.NAOK == "A" || Q_Question2.NAOK == "B" || Q_Question2.NAOK == "C"), otherwise the user will be screened out. This condition is not supported by Quota, therefore my only solution would be through Relevance.

This method works fine and screens out respondents as it should. However my question is that although the respondent get screened out, LS recognizes the response as COMPLETED whereas it should have been INCOMPLETE as the respondent get screened out. Is there any alternative where we can still use Relevance but yet the screened out respondent is marked INCOMPLETE as it should?

This question was already asked earlier by Holch but remains unanswered.

Of course I could apply a condition to every single question following, but as the screen outs usually happen within the first few questions this would mean to copy this condition to all questions that follow. Additionally, this would mean that the person actually is registered as a finished interview, which shouldn't be.

Hi
A the very beginning of the questionnaire, I want to screen out respondents who answer a "yes/no" question (their are not the target of the survey). I created a quota with quota "0" and action "terminate questionnaire". But even when I fill the condition (answer "no"), there is no screen out (the next page is proposed, with the button "next", etc.).

What did I miss? what is wrong?

Thank you!

New user of LS but with the will to contribute to this great community !
