==================
Is it possible to use this as question validation in combination with an array filter? I've tested using unique(self) without and it works, but once I add an array filter it appears to always fail

I've attached a copy of the survey where this is not working for me

 

Try unique(self.NAOK)

It is quite obvious that it doesn't work this way.
If you only select two or three items in Q1 you only rate these in Q2. The rest of subquestions has the same value -> not unique.

Please, read the manual about ".NAOK"

With the correct validation equation "unique(self.NAOK)" and a validation tip it is fine.
   



Last remark: Do not use the Condition builder, use Relevance equations instead.
Read here about the Pros and Cons of both.

By the way: Your relevance equation of Q2 is not necessary. This is done by the array filter.


A last word. Is it really necessary to force your respondents to click twice for each answer (drop-down-Layout)?
Why not the usual array layout?

Thanks!

Apologies - this is just a dumbed down version of the real question as an example. I'm using dropdowns as the answer options are shown/hidden using javascript based on how many options were selected at Q1 and which answer options have already been used at Q2. I think it looks cleaner to have this interaction hidden under the dropdown.

Agreed.
