Thank you for your answer, but I still don't undertand yet.
So: I have a question Yes (igen) and No(nem) and more than one answer (U can see it in the picture). and I want the Q2 question have only the selected subquestions marked as 'Yes' in the previous Q1 question. If I would have just One answer i used to the Array filter, but it's not working now. And the relevance equation not editable because i have another condition. What should i have to do?

Well, if I understood you right, then your problem is actually totally different to what was originally asked. You want a question pre-marked depending on the previous question, if I understood you right?

The OP wanted to show only those subquestions in Q2 that received a certain answer in Q1.

That's what I want: it was the original problem in this topic (the one different that my Q2's type not text, radius) : "Q1 is an Array question with Yes/No answer options; Q2 is an Array (Text) question. And I want the Q2 question have only the selected subquestions marked as 'Yes' in the previous Q1 question.

So, I've put an Array_filter in Q2 question with Q1 code question, but the problem is that all subquestions appear in Q2, as such whether the answer is Yes as No."

I added a file (image) with az example: I just want to see Q2 what in Q1 was marked yes(igen). i don't want to see in Q2 what was No (nem) in Q1! Does it possible? Arrey filter doesn't work!

Your example wasn't very helpful in the firstplace, because it didn't show the full picture (question 2 not showing).

The problem is that the array filter doesn't work with array questions as source, only multiple choice.

If you can't use multiple choice for the first question (I don't see why you couldn't), then you need to use relevance equation on subquestion level comes into play.

Go to question 2 and have a look at the end of the line, there should be the option to open a field to put the relevance equation (Symbol is an arrow).

I will see if I can make an example survey.

Here a question group with the two questions as example. With that you should be able to get your example done.

I'm really grateful your help, but i stucked with the program, it doesn't open the file. Error message:

"The languages of the imported group file must at least include the base language of this survey."

The group Holch provided is for an English survey. Create an English test survey and import it there.

@Holch: thank you very much! It is cool. Just I didn't know what i had to write in this box! It's not to easy to me, but i think i will can with other questions to. If I think well I have to type this every time: question group code_question code_=="answercode what i want to show"

@tpart: Thank you! We can open the file!

Thank you very much!! :kiss:
