Hi all,

I have a question about pre-define the variable with Token attribute. (e.g. showing the answer of last year)
The responds cannot be change.

For example, I used TOKEN:ATTRIBUTE_1 to pre-define Q1. The pre-defined answer is Option 1
Then I change it to Option 2 and it works.
However, if I close the browser and go to the survey again, Q1 changed back to Option 1.....


This is my step, may I know if there are any thing wrong....Thank you very much...
I will create "Equation" and "Radio"
Q1 is the radio question and this is the equation I am using:
Q1 = if(is_empty(Q1.NAOK), TOKEN:ATTRIBUTE_1, Q1.NAOK)

I allow the respondents update their responses:
"Allow multiple responses or update responses with one token: On"


It works fine if the respondents did not close the browser. But if they want to update their responses and go to the survey again, it change back to TOKEN:ATTRIBUTE_1

Thank you very much!
Kevin

I think you must use Q1 = if(is_empty(Q1.NAOK), TOKEN:ATTRIBUTE_1, Q1.NAOK) only in an hidden equation question type before the Q1 question.

See : manual.limesurvey.org/Expression_Manager..._Assignment_Operator

Hi Denis,

Yes, I set the "Equation" at the beginning.
It is working at the first time. But if I want to update the answer, it change back to ATTRIBUTE_1

By the way, "if" is missing in the manual, am I right?
Set a default answer to an array question type at start of a survey : {Q1_SQ1= if(is_empty(Q1_SQ1.NAOK),"A99",Q1_SQ1.NAOK)}
Set a default answer to an array texts question type at start of a survey : {Q1_SQY1_SQX1 = if(is_empty(Q1_SQY1_SQX1.NAOK),"Inserted answer", Q1_SQY1_SQX1.NAOK)}

Really strange ,

You really update answers ? answer persitence are set to Yes ?

What is your limesurvey version ?

Denis
PS : manual fixed, thanks you

Hi Denis,

I am using Version 3.21.1+191210

This is my demo, the answer cannot update...
aristosurvey.com/LS/index.php/855196?newtest=Y&lang=en
Token: 1234

Thank you!
Kevin

Arg !!

Your right … bugs.limesurvey.org/view.php?id=16230

Can you report the issue for 3.X too please ?

Hi Denis,

Thank you.
I saw that "3.22 have the same issue", so it should be fine.
May I know if there are any alternative solution to solve the issue?

No : it means the bug are in 3.22 too …

I don't find it…

Could we Pre-define the variable with Javascript?
Set the display condition of the Javascript (e.g. put it into "Equation").

If so, may I have an example of pre-define the variable with Javascript?
Thank you very much!

There are an alternative, but it don't work in Question by Question mode : in group by groupmode : put the equation after the question, but in same group …

for javascript … something like this :

Thank you so much! It works!
How about other question type? (Array, Multiple choice, Text input). I think the example is fit for radio question only.
Is there some example/manual/guide to follow? Thanks.
