i think it doesn’t work because you’re using Create Widget and Add to Viewport inside the timer function, you’re creating and displaying more than one widget per second on the hub because the timer function is called 1 time per second when the player start overlapping the box, so i think you’re creating and displaying a LOT of widget on the same position.
so remove the Create Widget and Add to Viewport from the timer function and Add it after begin overlap, I need to go to work now, try this and let me know, if you can’t make it work I will try to replicate your blueprint more accurately.
