Trying to set a block to a specific location, but it's just not working

[PlaywithK]

I try to make a OneBlock like Game in the nether, where you mine one specific block and it's replacing itself over and over.
I don't get any errors but it just won't work. Did I do something wrong?

Code:

on load:
    set {_blocklist::*} to netherrack and nether_quartz_ore and nether_gold_ore and nether_wart_block and ancient_debris and soul_sand and soul_soil
    set {_oneblock} to a random element out of {_blocklist::*}
    set block at location 0, 64, 0 in world "world_nether" to {_oneblock}
    broadcast "Block in list is %{_oneblock}%"

on mine:
    if event-block is {_oneblock}:
        if block at location 0.5, 64.5, 0.5 in world "world_nether" is air:
            broadcast "SUCCESFULLY LOCATED"
            set {_oneblock} to a random element out of {_blocklist::*}
            set block at location 0.5, 64.5, 0.5 in world "world_nether" to {_oneblock}

Thanks for every answer <3

Hello, try this:

on load:
    clear {blocklist::*}
    add netherrack and nether_quartz_ore and nether_gold_ore and nether_wart_block and ancient_debris and soul_sand and soul_soil to {blocklist::*}
    set {oneblock} to a random element out of {blocklist::*}
    set block at location 0, 64, 0 in world "world_nether" to {oneblock}
    broadcast "Block in list is %{oneblock}%"
    set {loc} to location(0.5, 64.5, 0.5, world "lobby")

on break:
    if event-block is {oneblock}:
        if event-location = {loc}:
            broadcast "SUCCESFULLY LOCATED"
            set {oneblock} to random element out of {blocklist::*}
            wait 1 tick
            set block at location at {loc} to {oneblock}
