Selection of a list

I would like to implement a list of various subtopics that participants can select, and after working through the list, move on.
I have tried to implement the following way:
Participants are offered various topics by the “select one” answer type option, answers are stored in a variable. According to an answer option, the corresponding dialogues should appear (by the function “message will only be sent if the following rules are all TRUE” adding the condition $session2RiskSubjectChoice text equals value “topic”).

But it does not work. Is it because I use several messages that should be sent if the rule applies? How can I go about this? See screenshots for additional information:

select topic

Please let me know if you need more info…
Thanks very much and best regards,
