Random Block Placement

[acktbt]

Hello. I am trying to place a cuboid with random blocks inside it (lets say cobblestone and stone) but i cannot figure out how to do it. I have tried some things but skript can't understand it so i'm trying to get help here. Please try and help as i've been trying for so long now and i've posted this problem on multiple different websites but no one gives a response. Thanks for any help! (BTW worldedit does not do the thing i want i want to do this inside a skript)

loop blocks within {_x} to {_x}:
    set loop-block to stone
    chance of 30%:
        set loop-block to cobblestone

    set loop-block to stone

        set loop-block to cobblestone

this doesnt seem to work with my skript and how would i put coordinates into this

its literally just vanilla skript and just exchange it with the local variables

I think this would be the simplest way for beginners

set {_loc::1} to location at 1, 1, 1 in world "xxx"
set {_loc::2} to location at 1, 1, 1 in world "xxx"
loop blocks within {_loc::1} to {_loc::2}:
    set loop-block to stone
    chance of 30%:
        set loop-block to cobblestone

it seems all good except skript is still returning saying it does not understand the loop "loop blocks within {_loc::1} to {_loc::2}:"
