Need some help.

I want to make it so that the screen is flat, not moving, three text inputs that will generate 4 outputs, the inputs go in and the run button is pressed generating the outputs… This will be used as a puzzle feature in a game.

XXXXX<---- Input 1
XXXXX<-----Input 2
XXXXX<------Input 3

RUN BUTTON

XXXXX<----- Is = to number 1
XXXXX<----- Is = to number 2 - number 1
XXXXX<------Is = to number 3 - number 2
XXXXX<------Is = to number 3

And, what’s the question?
Have you made GUI already and have issue with the BP. Or in contrary, have an issue with the GUI?
