Make a question required conditionally based on answer to previous question

[BrentKinal1]

I asked this a while back to no avail and question came up again so I thought I'd try give it another try.

I'd like to make a question conditionally required, that is I would always like it to visible however if a previous question is answered a certain way I would like the question to be required. Does any one know if this is possible?

Here is a link to my original question: Survey 123 Conditionally Required Question

Has there been any progress for allowing this functionality in the Web form?

Hi. Yes. This has been implemented. Make sure you use Survey123 Connect version 3.11 or newer for this. This works in both the Survey123 field and web apps.

Attaching an XLSForm illustrating how this can be done.

type	name	label	required
select_one yes_no	nextrequired	Make next question required?
text	comments	Comments	selected(${nextrequired},"yes")

Hi there,

I know this was from a while ago, but I was wondering if the ability to put a function in the required section has changed at all. I'm trying to do so, but it is only letting me pick yes or leave blank. I am on version 3.15.170 and I am just trying to make it so that the question isn't 'completed' until the value is = 100. Cheers!

Hi,

i have used this if statement in the required field: if (${Type_Suivi}='Elimination','yes',''), where Type_Suivi is a select_one question. I also have conditions in the relevant column for that same question. I am not getting a required question when using the form. The only way I can have this question required is when i remove the if statement and the relevant expression. Any clues?

[DougBrowning]

The statement must evaluate to True not 'yes'.  You can pull this off using 1 and 0.

Use this 

if (${Type_Suivi}='Elimination',1,0)

[ReneAubut]

Thanks Doug! Just had it working also using: ${Type_Suivi}='Elimination'

[DougBrowning]

Opps I was writing Ifs all day so I forgot.  Same though - evaluate to true.

How I use if in relevant is things like if(${state}="WA",${Type_Suivi}='Elimination',0).  This is having a relevant only for certain situations.

Sorry about that

I really need the conditionally relevant feature, so definitely bump this up on your enhancement priorities.

Without knowing what workflows you're using, this method is one that I've tried with some success:

1. Take the question you want to be conditionally required and make a second copy of it.
2. One copy is marked as required, the other isn't.
3. Each copy has a relevant condition such that only one copy will display. In the case of the required copy, this will be the condition you have in mind that makes this question required.
4. Set both copies as null
5. Have a read-only or hidden question populate with the answer of the above two copies, using an if/then statement based on your original requirement condition. This keeps both of the above copies' answers in the same field.

type	name	label	relevant	calculation
select_one yes_no	IsRequired	Should this question be required?
text	NotRequired	This question is not required.	${IsRequired}='no'
text	Required	This question is required.*	${isRequired}='yes'
text	Result	This field stores the values of 'Required' and 'NotRequired'		if(selected(${IsRequired}, 'yes'), ${Required}, ${NotRequired})

Great work around Nick!!! Thanks for sharing, this will be a regular part of the workflow in many forms.
