Solved Every x amount of zombie kill

[SaltyPotata]

on death of zombie:
    add 1 to {zombieDeaths}
    if {zombieDeaths} is greater than or equal to 3:
        set {_drops} to player skull named "&5&lZombie Boss tojás" with nbt "{SkullOwner:{Id:""75d0cf8a-cfd2-48b5-bc44-513347a526fb"",Properties:{textures:[{Value:""eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzdmODQ0YmZlYTI1NDI5ZDQ1ZTFmY2Y5NmVmNjY1NGRmYWFhNmZjOTAyZGMxYjZiNjhjMGFiYzEzNDM0NDcifX19""}]}}}"
        set {_zombielocation} to victim's location
        drop {_drops} at {_zombielocation}
        clear {zombieDeaths}

This is not working and I have no idea why. Can someone help me out?

Change:

set {_drops} to player skull named "&5&lZombie Boss tojás" with nbt "{SkullOwner:{Id:""75d0cf8a-cfd2-48b5-bc44-513347a526fb"",Properties:{textures:[{Value:""eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzdmODQ0YmZlYTI1NDI5ZDQ1ZTFmY2Y5NmVmNjY1NGRmYWFhNmZjOTAyZGMxYjZiNjhjMGFiYzEzNDM0NDcifX19""}]}}}"

To:

set {_drops} to attacker's skull named "&5&lZombie Boss tojás" with nbt "{SkullOwner:{Id:""75d0cf8a-cfd2-48b5-bc44-513347a526fb"",Properties:{textures:[{Value:""eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzdmODQ0YmZlYTI1NDI5ZDQ1ZTFmY2Y5NmVmNjY1NGRmYWFhNmZjOTAyZGMxYjZiNjhjMGFiYzEzNDM0NDcifX19""}]}}}"

Btw, this is working for me:

on death of zombie:
    attacker is a player
    add 1 to {l_zombieDeaths::%attacker%}
    if {l_zombieDeaths::%attacker%} is greater than or equal to 3:
        set {_drops} to attacker's skull named "&5&lZombie Boss tojás" with nbt "{SkullOwner:{Id:""75d0cf8a-cfd2-48b5-bc44-513347a526fb"",Properties:{textures:[{Value:""eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzdmODQ0YmZlYTI1NDI5ZDQ1ZTFmY2Y5NmVmNjY1NGRmYWFhNmZjOTAyZGMxYjZiNjhjMGFiYzEzNDM0NDcifX19""}]}}}"
        set {_zombielocation} to victim's location
        drop {_drops} at {_zombielocation}
        delete {l_zombieDeaths::%attacker%}
