Fire an event from another blueprint

Good Afternoon.

I am trying to fire an event from another blueprint and to make it as simple as possible I wanted to use a variable that reference the target blueprint containing the event like so :

6070-target.png

But when I try it, it doesn’t fire the event in the target blueprint, I am sure I have connected the right target blueprint to the variable but it doesn’t react, Is there a better way to do it ?

Thank you
