Effekty

command /ekt:
    trigger:
        open chest with 3 row named "&4Efekty" to player
        set slot 0 of player's current inventory to speed splash potion named "&fStrength" with lore "ss"
inventory click:
    if inventory name of current inventory of player is "&4Efekty":
        if clicked slot is 0:
            cancel event
            player's balance is more than 1000
            remove 1000 from player's balance
            apply speed 2 to the player for 50 second

Czy dało by się zrobić żeby effekty nie dodawały się do siebie?
