Is it possible to automatically deactivate the survey when it reaches the number of 250 participants?

Hi,
you can use quotas ... this won't desactivate the survey but stop collecting more responses

Unfortunately this feature doesn't exist out of the box.

What you can do is use quotas, as Ben suggests. But it is not that simple. Because I assume you want to close the survey when you reach, let's say n=1000 cases.

Now you would need to apply a quota to a question to identify if you have already 1000 responses over all.

At the moment I can just imagine one option: A hidden question with exactly 1 answer that is triggered by some expression or javascript for ANY given answer in the first question.

You should be able to handle that with the default answer setting on a list-radio question.

Sounds reasonable. This is probably the currently the simples solutions to close a survey based on the number of total responses completed.

For "quota" withour real answer : i really think we must test the Yes/No question : this question type accept default value by Expression.

Seems the simpliest solution :
- only one question (no A single choice + Equation)
- Each Y/N question can have own quota : more clear in quota listing
- Really logic and understandable

Why not a list-radio with a single answer option set by default as I suggested? Is that not the same as your suggestion?

I agree with Tpartner. A list-radio with only one answer option, which is set as default, and the whole thing hidden as the first question looks as the simplest approach to me to have a cut at a certain amount of total interviews.

Denis, your solution sounds a more work/complicated than the solution from Tpartner, or do I miss something?

Hi,

Here : a liots radio is OK, but i thinking more for other option : example :
Age : numeric question type
Gender : M/F

We want a restriction on M less than 18.
Use a Yes/No question with default value set to {if(Age<18 and Gender=="M","Y","N")}

Thisnk it's more easy. I have to make a demo survey and send it to the wiki somewhere (quota + EM + YN question)

I agree, for your example this is a good option.

But for a global limit like requested here (close survey when a total of n=250 completes is reached) the solution proposed by Tpartner seems like the best and simplest solution.

However, your solution is a great example on how to create more complicated quotas. I very much like that idea when quotas are complex and involve different questions. Hiding the question in the advanced settings should still allow this default value to be triggered, right?

Yes, if you want more complex quota requirements, your solution is the way to go. My solution is for a basic maximum number of participants as the OP requested.

Sorry, it's the bad topic. In fact , i just want discussion with holch and tpartner .
