Hi everyone!
I’m currently designing a study with 18 different conditions. Each condition (or question group) must have the same quota based on 5 sociodemographic questions. 
From what I know about LS, I’m gonna need to implement around 522 quotas questions (29*18), which appears to me as a tremendous waste of time and energy…
is there any way to only create 29 quotas and apply them to the 18 question groups?
thanks for your answers !
best regards,

Raphael

You seem to misunderstand the meaning of quota.
So, first you assign the participant to one of the 18 groups.
There are 5 demo questions in each of these groups.
And then do you really want to screen out people because their answers to these 5 demo question overquote?

I do not believe this.

I think there are 5 demographic questions at the beginning and then the repondents are distributed to different groups. And here you have a quota, like "each group 50 respondents, 25 male, 25 female, or so.

So, please clarify, what exactly you try to do.

Well, maybe i'm using LS in quite an unconventional way.
In this study, the participants are first assigned to one of the 18 different question group or condition. Each condition must have exactly the same population. So, at the beginning of each question group are sociodemographic questions used to screen out participants who do not conform to our target sample.
So I'm trying to design quotas for each answer to these demographic question.
I already designed quotas for one question group (so 29 quotas based on the different possible answers of the sociodemographic questions), which took me quite some time. And now I'm supposed to do the same for all the other question groups.
From my calculations, doing so by creating one quota for each answer in each question group will take me around 5 or 10 hours.
I'm looking for another way to assign a maximum number of respondents based on sociodemographic questions to each of my conditions - like some kind of copy/paste button for quotas.

I hope this makes it more clear.

And maybe i'm doing this the wrong way, i'm self taught on LS so my approach may be a little strange sometimes.

Hi, 

are first assigned to one of the 18 different question group or condition

At random?
In this case you should consider a different approach.
First check by the demographic questions into which of your 29 quota groups the participant is.
THEN select the least filled group of the 18. 

Then there is this thread about a similar question a few days ago.
[url] forums.limesurvey.org/forum/can-i-do-thi...add-quotas-massively [/url]

I would do it like Denis.
There are only three tables in the database involved.

If there is more time I'll try to show an example.

P.S.
As usual the best, you show a prototype of the survey as lss export.
AS you said, you already finished the quota of one group.
Maybe we find a better way.

If that really is the case, then you need to ask each group to everyone in the survey... ;-)

I assume you want the same sociodemographic structure for each group.

Thank you for all your answers.
I finally just duplicate my studies making one per condition.
It's probably not the smartest way to do but this was clearly the easiest way based on my abilities.
