I want to do a Multiple Numeric Input question but as an array, like the Array Numbers question type, but where each column of answers sums to 100, as I can do with the Multiple Numeric Input. Is this possible?

To see what I mean, here is what it would look like



The "now" and "future" columns should sum to 100, no individual answer should be greater than 100 or less than 0.

Is this possible?

Yes, you can do this easily.

Here is what it looks like running:



Here is the question design view:



For the help text, you enter the following:
and this expands internally to look like this:



Here is the actual question as a .lsq file



The Expression Manager documentation explains how to use the self variable in more detail.

I neglected the requirement that that each value be between 0 and 100.

Here is the corrected question as .lsq file:




And the associated screenshot showing that it works:



The rest is the same.

Thanks for your replies to this and sorry for my late response. I didn't receive a notification that someone had responded to this thread.

I have tested out your question example and it does work very well.

Cheers.

Hey there,

I need Sum Validation in an array (numbers) for LimeSurvey Version 3.13.2+180709. It should work like the "equals sum value" in "multiple numerical input"-questions.

How can I do that?

You can do any control with manual.limesurvey.org/Question_type_-_Ar...28em_validation_q.29

Hi,

see my answer to your other post about this
