Skript won't commit

[left osprey]

    trigger:
        set {_loc1} to location(40, 65, 40, world "pvp")
        set {_loc2} to location(-40, 84, -40, world "pvp")

        loop blocks between {_loc1} and {_loc2}:
            if loop-block is not gold ore:
                set loop-block to air```

it doesnt give any errors but neither does it do anything

you probably want blocks within

between creates a line
