Hello everybody my name is David. I am very happy to have the possibility to write here.
Hope I will get help in solving my problems

My question is the following:
Question 1. Which TV channels do you watch? – multiple chois
Question 2. Most often consumed? - multiple chois ( But in the answers to this question I want to show only the answers that were mentioned in the previous question)

Hi @David_Shoshitaishvil,

You can build these cascading selects using https://docs.getodk.org/form-logic/#id71.

My guess is that you want to the second question to show only what was selected in the first? If so, see below.

Ranking importance of a previous question's answers (multiple answers)

If you're using the same list, and want the second question to only show options that were selected in the first question you can use add a choice_filter column with a value of selected(${buyers},name) for the second question. More details in this forum thread about Choice filter with multiple selection.
