How to divide a health variable by same amount of itself when it is constantly changing ?

Its on the enemy i followed this guide https://www.youtube.com/watch?v=BpTKS5-9KnE

The player does damage with simple damage interface

i add the damage for example here on my main attack

and here is the widget on the enemy and it has external widget BP for it

So after following the health widget guide above the enemy’s head it works flawlessly just like on the tutorial problem is he awso has fixed amount of life i think 100 and then he divides that by 100 so progressbar moves as it should. This is the case for me too but the life increases of my enemy’s so this works only for the first wave of monster spawn. Basicly all i need is to change this like you showed me but i cant get the variables ref to them correctly in the widget BP when i try to get them from the enemy.
If i cant do that i should try to move the widget progress bar not calling it from the “bind” function on the widget but on the enemy where the correct variables are and updating correctly i think if i can make it to show up from there it may work.
