Hi,
I'm here to ask some tips regarding the question type called:"Array (Numbers)"
I have one question with a lot of Y subquestion and only two X scale selection available with a checkbox, A or B.
What I need is to force participants to select only A, B or leave unchecked each Y subquestion. With default settings the users can check both A and B for each Y row.
In additional to this condition, I need to validate and let the users proceed only if they have checked only ten "A" subquestion, and five "B" checked.
Actually I'm using advanced option and I've set both minimum and maximum answers to 15, but in this case a people can select 15 "A" option without any B selected without any warning.

I know that using javascript it's possible to do almost "everything", but I'm asking if it's possible do this using the advanced settings option provided by default by the Limesurvey.

Thanks to all like usual

Hi,

You must use www.limesurvey.org/manual/Question_type_...28em_validation_q.29

For "f they have checked only ten "A" subquestion, and five "B" checked"
Something like this For "What I need is to force participants to select only A, B or leave unchecked each Y"
Why ypou don't use an array question type ?
ELse you can do : The finally: There can be soome error , but can be tested and improved

Thanks for suggestion,
I'm using the Array Numbers Type because I think for the users is better to have the checkbox, with the ability to clear his answer simply clicking again on the checkbox.
With the array type using radio button I have not found a simply way to allow user to clear a selection.

I'm now playing with the validation equation, but I have some trouble interpreting the meaning of: "self.sq_A"

What is exactly "sq_A"?

My question is made by a lot of sub-question Y scale, with code r1,r2 and so on.
And only two sub-question X-Scale, with code A and code B.

For example I try to change the code to "(count(self.sq_r1.NAOK) < 2)" but it's seams doesn't work, I'm not sure about the meaning of "sq_" and how to change for my question.

sq_X - where X is a row or column identifier. Only sub-questions matching pattern X are selected. Note that search is done on complete code identifier, then sq_X match and include subquestions nX, X, Xn (e.g. if you use sq_1, subquestions a1, 1a, 1, 11 or 001 was included). Put attention at dual scale question type where subquestions code are QCODE_SQCODE_1 and QCODE_SQCODE_1 and to ranking question type where subquestions code are QCODE_1,QCODE_2 ....

www.limesurvey.org/manual/Expression_Man....27that.27_variables

You see the final formula in expression logic file , maybe you have r1 and r10 and r11 etc ....

Thanks for the TIP and the link, after changing some subquestion code to prevent missmatch, and making some test, I think to reach the code that I need to use, but unfortunately seams not works inside validation code box.
To make a test I write in the question the code to live view what the system counts, and the code seams works fine, but unfortunately the same code used inside validation box seams not work.
Here some screen of what I'm doing.




Thanks for any support.

Place your equation in the "Question validation equation" field under "Advanced settings", not in the "Validation" field - that's a legacy field for Regex's.

I can't believe! I lost the count of many times I've try to edit my code, and finally the problem is not the code but the box that I'm using!

Thanks for support, I'm pretty new with this wonderful tool

I've finally put all the code together, and the validation works fine.
The only think that I would like to improve right now is the option for each row.
At the moment the user can check both A or B option, and got an error message when try to go in the next step or submit the survey.
It's possible to insert a javascript to "emulate" the same experience of radio box array? I would like to move the selection instead allow the multiple selection.
I don't know if, with this purpose in mind, it's better ( and easier ) to use normal array question type and changing style from radio radio button to checkbox, or add a "moving" rule with javascript to this array (number ) type.

If I understand correctly, you want only one checkbox per row clickable.

Adding this script to the question source will automatically uncheck all boxes in a row when a new box is checked:

Finally, all seams works really fine,both for users experience and data consistency. Thanks

automatically uncheck all boxes in a column when a new box is checked

could you help me？
