Hello,

I have read through the manual and forums and I am not sure how to do the following:
I have an array texts questions where I am trying to make it so that the respondent has to fill out at least one of the rows, it doesn't matter which. I', also trying to make it so that they can enter numbers or texts and still the same would apply.

Would really really appreciate help with this!!

 

You can use the Question validation equation in edit-logic-validation equation. by something like {!is_empty( Qcode_SQ001) or !is_empty(Qcode_SQ002) or...}

Hello,

Thank you for your response!It worked for one of my questions but weirdly enough when I did the same thing for another question, it keeps saying that I have an undefined variable. Any ideas why?

Thank you very much.

For reference, this is what I have in the Question validation equation:!is_empty(p51_p51a) or !is_empty(p51_p51b)   

Hi,

I think it is because this is an array-text question and there are subquestions for both columns and rows. So you should write the code in this way : Qcode_Y_X. So it should be: (! is_empty(p51_p51a_a) and ! is_empty(p51_p51a_b) and ! is_empty(p51_p51a_c) and ! is_empty(p51_p51a_d))or (! is_empty(p51_p51b_a) and ! is_empty(p51_p51b_b) and ! is_empty(p51_p51b_c) and ! is_empty(p51_p51b_d)) to make sure at least one row is fully filled.

@LISHANGQI is absolutely right.
Please, read again the manual about the question codes naming
[url] www.limesurvey.org/manual/ExpressionScri...code_variable_naming [/url]
And if you read about the variables "self" and "that"
[url] www.limesurvey.org/manual/ExpressionScri....22that.22_variables [/url]

you may shorten your validation to
count(self.sq_p51a)==4 or count(self.sq_p51b)==4

I am always wondering about this doubling of codes.
Why do you code the y-axis again with the question code, so in your dataset you get "p51_p51a_a"
In my opinion better: y-axis "Y01", "Y02",... or "YA", "YB",... and the x-axis "X01", "X02",... 
This is a big advantage when using "self" and "that"
 

Wow, it is a much better solution!

Hi Joffm,

Thank you so much you are a lifesaver. Yeah it's just how we need it for our codebook.

I want to use the same principle and apply it where I have an array (radio) question and want rows 1-4 mandatory. Therefore, could I use this same principal and instead of using 'or' I use 'and'. Would I be missing something by just simply doing this? I did test it out and it's not working which is why I believe I am wrong somewhere.

Thank you.

Thank you for your response @lishangqi!

Hi,
I hope you understood how the "self" and "that" variable work.
And keep in mind that an array(text) or array(numbers) are two-dimensional - subquestions in y-axis and x-axis, answers in cells.
But an array is one-dimensional - subquestions in y-axis, answers in rows (or x-axis)

This means if you code the subquestion in a useful way like
M001
M002
M003
M004
O005
O006
meaning "Mxxx" is a mandatory subquestion, "Oxxx" is a optional subquestion.

Then obviously the count of answered M-subquestions has to be 4 to fulfill your requirement.
count(self.sq_M)==4

Of course you can do it the other way enter all subquestion codes like
count(Q1_SQ001,Q1_SQ002,Q1_SQ003,Q1_SQ004)==4
but  "self" and "that" are really mighty and save a lot of work.

Ah okay I see, thank you!
