Your LimeSurvey version: Version 5.3.6+220321Hey guys!
I need some help here.

In a list radio I need a fixed answer option to always appear and I need to randomize a second answer possibility among 27 options.

I'm trying to do this with the filter array but I'm not getting it, can you help me?

Also, I have another question: how can I put the maximum number of characters in an "others" option of a radio list question.

Thank you so much!

Here the lss file

Hi,
1. There is a typo in your creation of the random number (missing comma)
2. By an array filter you show the "selected" subquestions in a next question. You do not select you only filter the display.
To use the multiple question as an array filter, you have to set the selected answer by an equation
Like:
{multiple_1=if(randnumber==1,"Y","")}
{multiple_2=if(randnumber==2,"Y","")}
{multiple_3=if(randnumber=,"Y","")}
...
{multiple_27=if(randnumber==27,"Y","")}

3. To limit the input in the "other" you have to validate.
Like strlen(QCode_other)<10

Joffm!
You are amazing! Thank you so much!

Just one more question: Would I be able to configure the two radio list response options so that the two are randomized in this way?
And in that case, I would need them not to be repeated.

so that the two are randomized

Meaning?
Once you display
Option 0
Option 4
and then
Option 4
Option 0

Do it in the settings.

I would need them not to be repeated.

When or what repdeated?
There is only one question.
