Adding Impulse to a ball

I want to make a minigolf game, plan is the ball gets a force in the direction of the cursor when i click.
So far i have a plane, a ball and two blueprints. One is my playercontroller for the mouse and the other one is my ball blueprint where i focus the camera on it and make a vector based on the balls position.

Now when i click, nothing happens. I’m pretty new to unreal, so please explain it newby friendly, if you need any further details i will provide them, just let me know.

Ok i figured it on my own, the problem was that i had a wrong target, read this:
