Hi,

I have survey with tokens (100 participants). Each of them has 50 devices with unique number. They have to provide number of the device (one per one survey) and do the survey for each 50 devices. I want to help them to block using the same unique number twice. How can I do it in the system? How to check if provided 6 digits number already exists in answer and was provided by specific token?

What?

Sorry, don't get what you are trying to do.

You cannot access the answers of other respondents during an interview.

Except if you use 4.X version : see www.limesurvey.org/manual/StatFunctions plugin

For example : {statCountIf(self.sgqa,self.NAOK) == 1}

remind : statCountIf and statCount work only on a second page : no javascript control.

Thank you. Does this function work for all responses or can be narrowed to responses for particular token user? What do you mean by "work only on a second page"? How to understand sentence from instruction "when move in survey"?

All response on self

Then you can create a equation question with (if you question code was Q01)
{TOKEN}{Q01.NAOK}
With code EqCheck

And use for validation : {statCountIf(EqCheck.sgqa,EqCheck.NAOK) == 0}


Then : user are allowed to enter 123 on Q01.NAOK only one time (need 0 : count submitted answer by default)



For next page / diffrent page: the function is done only when user click on move next/ move previous/ save etc …

DenisChenu. Great. Thank you.

You use 4.X ?

If yes : please tell us if it work : its really a new feature, we have a test on it but need some idea

Actually I use older version but have to download 4.x:-). Also I have an issue how to automatically upload dropdown lists based on tokens. I have survey 1 which can be answered 50 times by each token. For example each token provides 50 different car plates numbers. In survey 2 I need dropdown lists containing 50 different car plates numbers specific for each token. It's easy to do it manually but how to do it automatically? Is it possible to use one question for all tokens and in this question has query which assigns proper car plates to token?

No, no , no …

Big warning : if you can : don't use 4X in production …
