Hi,

I am trying to apply array filter or Array filter exclusion from a radio question to Array question, but not having success.

The answers are in s4, and I want to apply array filter in c6 and array filter exclusion in c7 based on answers on s4
similarly from answeers in c5 i want to apply array filter to c6a and array filter exclusion to c7a.

I am attaching my LSS if someone can share help.

Well,
s4 is a single punch question, there is no array filter.
You can insert into the subquestion relevance of c6:
Sky: s4==1
Virgin: s4==2
...

And for the exclusion:
s4!=1
s4!=2
...

c5 is a matrix.
So which answer option shall be included in the array filter?
Again use subquestion relevance:
Let's say: people who answer "Yes" are included
In c6a:
Netflix: c5_14=="Y"
...


Here is what the manual says about array filter:

Array exclusion filter (array_filter_exclude)

Description

The Array filter exclusion setting allows you to use any multiple choice question to select or set which responses are NOT displayed in a subsequent list, array or multiple choice question.
The subsequent questions can be filtered on any array question type, including:

Multiple choice
Multiple choice with comments
Multiple short text
Multiple numeric
Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, Column)
Array (Dual Scale, Text, Numbers)
Ranking

Furthermore, each of these types of questions can filtered.
The only exception is Array (Column), which can filter other questions, but can not itself be filtered.

How to set it up

Enter the question code of a multiple options question in the array exclusion filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the non-selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array exclusion filter' box to start the filtering process of the answers. Only the answer options that are NOT selected in question Q1 will be visible in your question.

And this is the way you could do it with array filter:
Create a multiple question similar to s4.
By an equation fill this question with the answer of s4.
Now you can use it as filter.


I always advice to import and study the sample surveys:

Thanks for the quick reply Joff, got the above, and i get that.
Just to confirm for Array filter exclusion on c7a i shoudl use something like this
In c7a:
Netflix: c5_14!=="Y"

similarily when I trying to apply array filter exclusion in St1b OR St1ca (radio questions) from S4, i don't seem to have a place to apply relevance. Any suggestions what i could do there

In c7a:
Netflix: c5_14!=="Y"

Equal: "=="
Not equal: "!="

similarily when I trying to apply array filter exclusion in St1b OR St1ca (radio questions) from S4 ...

Of course not.
St1b is single punch.
There is no subquestion relevance.

Workaround; As said before. Create a multiple question like s4, (MS4)
By equation (eqMS4) check the answer:
{MS4_SQ001=if(S4 == 1, "Y", "")}
{MS4_SQ002=if(S4 == 2, "Y", "")}
{MS4_SQ003=if(S4 == 3, "Y", "")}
...

Afterwards you can use MS4 as array filter.

HI Joff,
Thanks for the support so far. I have managed to make C6 & C7 work, however still stuck with St1b

I have created a new multi select question hids4, where i am trying to punch in the response from s4. ( the latest export of survey is attached)

it looks like being a very novice user, I am making some basic mistake or not understanding something fundamental in the logic. if you have any step by step instructions, or could send me an example of how you would construct the same logic using 3 such questions that will be great, and very helpful.

Hi, small example.



I saw some mistakes around s4:

{eqhidS4=if((s4.NAOK=="A1"),'1','2')}

s4 has no answer option "A1"; s4 has answer options 1,2,3,...

hidS4: that was a misunderstanding on your side.

Joffm

And always remember:
To use array filter: Both questions have to have exactly the same answer options.

Hi Joff,

Thanks , could you please send the LSS again, it didn't come through right. shows 0KB, and can't be imported

I am using 2 questions after s4.
eqhids4
&
hids4

I am using eqhids4 to punch a quota of specific TV users vs non users from S4.

I added hids4 for create the multiple question solution you previously suggested. so trying to add relevance there, and then use hids4 to array filter questions like st1b,st1d,st1f etc.

the LSS file you sent as an example seems to be corrupt, so if you could send that again as well please.

thanks for looking into this and your support so far. excluding answer options from S4 into questions like st1b, st1d seems to be the last blocker i need to overcome.

ok, sent again.



If you still can't import it, I will sent a written manual for these four simple questions.

Hi Joff,

Thanks for the LSS. I have managed to replicate, and make the questions work.

Thanks a lot for your help, specially on a weekend!
All the best
