Simply Toggle a HUD on a collision.

Hey!

I’m returned to UE for a new project, and looks like I forgot everything I’ve learned in the previous ones.

So what I want to do, it a simple HUD that toggles on when the player reaching an area, where you can find an interactive object. So it is showing theres something, but on the rest of the map it is turned off.
So I am using the FPS starter kit’s HUD, and put in a variable that toggles it on and off. And I want to change this variable in the level BP, on an overlap event. Can someone help me finishing this node tree? Or if you have any better, simplier solution, I would be really thankful for that.

Thanks!
