Connect Multi-select question to Integer

Hello,
Please help, I’m new to using this software. So, I have a query about connecting Multi-select question and Integer type question.
My main question is of Multi-select type, since there should be more than one answer choice, each answer should be associated with a field which should be of Integer type and can be displayed whenever the answer in question is selected.

Thanks for the help in advance!

This usually depends on the survey.

If you are asking about household assets/appliances - then a multiselect question is handling the presence of the items, and a numeric question in a roster then is used to detail the number of selected items.

Alternatively one could use a numeric question in a fixed roster with a special value for 0=None.

Possibly other layouts.

Best, Sergiy

The specific survey is about airports, but I’ll probably need it in a household option as well.
My query about the multi-select questions was because more than one answer should be able to be selected, with a new amount/number input field opening for each answer.
Which option should I link it to, as it gives it as an error if I use Enabling condition and Validation condition?
I apologize in advance for the elementary questions, but I’m new here and still learning how to use it.
