How do I enter a variable from another blueprint into a viewport binding

Hi, i am asking how to enter a variable from another bp (my level bp) into a biding of a text object on a viewport. For context, I am trying to make a score system. In the level bp every time certain events happen the score variable increases. On the top right of the screen is the text which should say the score. How do i update the text to reflect the score?

I am also new so sorry if this is really dumb.
