Enchanting custom armor breaks script

[lowjector]

Hello, I recently created custom armor for a server. It works perfectly fine when it's not enchanted. However, when I enchant it the script completely stops working and it acts as if it's just regular leather armor. I can't see why this would happen.

My skript:

on damage:
    if victim is a player:
        set {_damage} to damage
        if victim is wearing leather chestplate named "&5Dragon Chestplate":
            set damage to ({_damage}*0.55)
            add -100 to victim's chestplate's durability

Thank you for helping.
