Widget reference won't work outside of blueprint

Hi all,

I have basically a very simple inventory system where when the player picks up an item, it will display on screen. I want it to be so when the player uses that item (ex. in this instance, a bucket of water) it will disappear from the screen. However I can’t reference the widget outside of its own blueprint (through a variable) does anyone have any idea how to do this?

setting the variable (the player collects water in this bp)


removing from viewport (different bp)

error:

Thanks!
