But watch out, as you are using open ended questions in your survey, brands might be there duplicated (in the open ends and marked in the list) and how do you choose the brand from the multiple choice question, if there have been marked more than one?
While technically possible, I think the question design has a few flaws.
Help us to help you!
Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).

Could you please collaborate on your question: " how do you choose the brand from the multiple choice question, if there have been marked more than one?"
I was hoping that some javascript magic would help me, but now I'm asking myself if it's possible to select "first selected" answer from multiple choice questions when there are more than one selected answer and how to approach it?
