Apparently, your script is not able to do this import. Have you properly compiled this message in the my_custom_srv_msg_pkg package? In case you have done so, have you added this package as a dependency of the services_quiz package?
In any case, I’d suggest you create this custom message BB8CustomServiceMessage in the services_quiz package (instead of the my_custom_srv_msg_pkg package), as it is requested by the Quiz.
from my_custom_srv.srv import BB8CustomServiceMessage, BB8CustomServiceMessageRequest
says that you have a package named my_custom_srv where you have created the custom service message. From what the error is saying (No module named ‘my_custom_srv’) and what I can see in your screenshot, it looks like you don’t have this package.
