Actor Z-location to UMG

Good day,
I’ve been trying to figure this out for a few days now, but I don’t think I’m using the right keywords because I can’t seem to find the solution to this beginner’s question.

So, sorry for my nooby question;

I am trying to display the Z displacement of an Actor (not the player but a bouncing ball) in a UMG widget, a Kantan Chart to be precise. But I can’t seem to figure out how to cast the location from the bouncing ball to the UMG widget.

I have created a User Widget called UMG.
Its Event Graph is as follows:

The UMG is created in the Level Blueprint and its blueprint is as follows:


Wherein I use the Variable ‘Actor’ to attach it with the bouncing ball and have it connected to the UMG-widget.

As result I get the following error (and no Z-location points):

Apologies for my poor English, it is not my first language.

Pull this pin

and set the actor variable INSIDE the widget.
