Hey @imlightbringer!
It’s not too far off the other type of commands you might have seen.
As explained here, you can generate a number between two values — both included — like this:
Math.floor(Math.random() * (max - min + 1) ) + min;
With that in mind, here’s how you can write the command to fit your needs, and you just need to replace MIN_VALUE and MAX_VALUE by the numbers you want:
$(eval min = MIN_VALUE; max = MAX_VALUE; Math.floor(Math.random() * (max - min + 1)) + min;)
