Can't reference variable from another script in my progress bar widget

So I am making a stamina bar for my game and everything has been working fine, I added the actual bar, made the stamina system and everything. Now I am just stuck on this ONE thing; binding the progress bar to the variable. For some reason just can’t reference the variable and use it in the function.


(You can even see I made a variable with the same setup in the event graph for the progress bar named “Char REF”) The variable (I named StaminaLevel) just won’t show up when I search for it in the function for the widget. Any help would really be appreciated.
