Redirecting people from a multiple choice question

if I interpret your requirement correctly, you want to direct to a different block, if any answer to that question has been picked - and continue in the normal flow, if no answer has been picked?
One option that would work with SurveyFlow is a multi-line condition with or. So, if your question XYZ has 3 options A, B and C, than the condition would be:
question XYZ answer A is selected
or question XYZ answer B is selected
or question XYZ answer C is selected

It's a bit tedious, but should work.

Different option with s slight design change would be to add a "Don't know / don't want to answer" option to your question (you could set it to "exclude from analysis", if needed) and then you use that answer to direct the flow. It has the added advantage that you could make the question mandatory, so participants don't accidentally skip it and end up in a block they shouldn't. But I'm aware that might not fit into your bigger plan, so first option would be it.

Hope I didn't misunderstand the context and purpose.

Dear All
Thank you very much for your input. I really appreciate it.

* The premise:
I have a multiple choice question.
* The issue:
If I try to apply branch logic to redirect people who have answered this question to another block, it does not seem to be possible. What I mean is that it is only possible if I create a branch logic for each of the answers.
If I had 'yes' or 'no' sort of question, the condition would just be 'if yes' or 'if no' is selected but, with a multiple choice question, it's a whole other story.....

Maybe it's a case of I don't understand how branch logic works. Fair enough. Still, I have read and re-read the tutorials for the different types of logic and this seemed to be the most suitable. I don't use Qualtrics often enough either (about once a year) ... so it's like having to relearn the tool every time.
