Textbox help

I’m using widgets to create a textbox. There are a lot of problems happening. Basically I need three things: for the box to appear when I’m in a box trigger and I press Z, to have it write out across the screen, and to be able to change the text from outside the blueprint without duplicating it a zillion times. Thanks, 2stooges.

[edit] I figured it out, turns out you just need to get the variable of the textbox in the blueprint and change that.
