How do I set text to the outcome of a "choose(1,2,3)"?

Making a damage system where the amount of damage done to an enemy taken shows up in text. When you attack said enemy, the amount of damage done is randomized (16,17,18,19). How do I get the outcome of

On Left Button clicked on "Hit" (attacking, basically)

--->Subtract choose(16,17,18,19) from "Enemy_HP"

to set the text to?

Use a variable to store the result of choose(...) and then you can subtract the variable from enemy hp and set text to variable.

Yeah, that's my issue. I don't know how to store the result.

Press 'v' to add a variable. Use the 'System: Set value' action to set it.

The above technique is the correct way of doing it... But if you want a shortcut and don't want to use variables for this, then just show "Text" first, and then subtract whatever value it chose and showed. Example:

Set Damage.text to: Choose(16, 17, 18, 19)

Subtract int(Damage.text) from "Enemy_HP"
