Communicate between Blueprints at given example

Hi at all,

I’ve watched all the “Blueprint Communication” Vids and read the Docs but there isn’t even 1 Example, which fits my needs.
I posted a detailed Question in AnswerHub: https://answers.unrealengine.com/questions/773568/communicate-in-given-example.html
I would appreciate if anyone could have a look at it.

best regards,
