==================
I am creating a survey with several matrix questions with dropdown answer options. The response to the question should be mandatory but it should not be mandatory to answer all rows and columns. Is this possible? How?

Thank you,
Ana

 

Hi, Ana,
is this a question of type "array(text)" with inserted dropdowns by javascript? Or what is it?
An array (dual scale) with dropdown layout?

but it should not be mandatory to answer all rows and columns

So the question can't be set to "mandatory".

The response to the question should be mandatory

Does this mean that at least one cell has to be answered?

This you have to do by "question validation equation".
Something like "count(self)>0".

But more after you send the lss export of this part of your survey.

Dear Joffm,

Thank you for your reply. Please find attached the question.

Best,
Ana

Hi,

after you send the lss export

We always ask for lss exports, neither lsq nor lsg.

And did you enter the validation equation?

Joffm

Hi. Here is the lss export. I did include the question validation equation but it does not work...

Hi,
1. you missed the validation tip




Well, I doubt that this  you consider as a correct answer (one cell of the entire array is answered.
But as you wrote

it should not be mandatory to answer all rows and columns.

2. Instead of setting this condition G2Q00001.NAOK == 1 (which is sufficient)  on each question of the group you'd better set in on group level

3. What regular expression is this? 
!G3Q00003{any=[G3Q00003-1,G3Q00003-2,G3Q00003-3,G3Q00003-4,G3Q00003-5,G3Q00003-6,G3Q00003-7]}

Hi again!
Thank you for your reply.
1. Ok. It is a good suggestion to add the tip
2. I'm sorry. I did not understand what am I doing wrong with the validation equation
3. The expression must have been inherited. I deleted it

Thanks!

what am I doing wrong with the validation equation

Nothing. I only wrote that I do not think that an answer as I showed in the screenshot should be a valid answer of this question.
