Stamina bar in UI

Hi all. So, i can’t find the error in my bp.
I made a simple stamina system, and its subtraction during the run of the character. When the character is not moving or is walking, stamina recovers(regenerates). But faced with a problem, hud does not display the fill bar of stamina.Sitting here I can not understand where I made mistake.

The screenshots below
As you see, stamina regenerates but ui bar dont fill up.

Oh…i solved my own problem)))
In widget code, I put a subtraction instead of division. Changed to division. Everything working.
