Adding validation Code/Rule

[mokech]

Hello Every one

I have this challange where i have set my question called Observation with the name Observation and it requires one to enter values Greater than Zero and less or equal to 3, (i.e 1,2 or 3 only) the validation is already set and working.

However my next question now is related to my Observation question (where options are 0,1,2,and 3), where if one inputs 3 in observation question, values 3 or 2 or 1 or 0 can be selected from my selection list, if one inputs 1 in observation ( only 1 or 0 can be selected from my selection list.

I have tried to put the validation .<= ${Observation} in this second question but it only works when one inputs 3 in the first question. when 2 or is put in question Observation the rest of the selection doesn’t work

Welcome to the community, @mokech! Is this something you are looking for that has been discussed in the community before:

Advanced skip logic

Hi @warrenmxt, you may find what you are looking for here in the docs. You can see this in action with the following simple example using the choice_filter column in the survey sheet: survey type name label choice_filter integer age_months What is the age of this child? select_multiple measles measles_dose i) Measles months < ${age_months} choices list_name name label months measles d1 Dose 1 9 measles d2 Dose 2 18

Hi @mokech, just to make the linked example relevant to your case, you can try something like this:

survey

type	name	label	constraint	relevant	choice_filter
integer	observation	Observation	. > 0 and . <= 3
select_multiple observations	select_obs	Select values		${observation} > 0 and ${observation} <= 3	name <= ${observation}

choices

list_name	name	label
observations	0	0
observations	1	1
observations	2	2
observations	3	3

Thank You so much, This has worked, My label was not written well, i had to change to the numbers and is perfect.
