[WiebeHero]

Well hello there i am WiebeHero and i am in need of help right now i have been trying stuff with nbt but it hasnt been working out so well im afraid...
1.The {_wantedItem} isnt really working out well because it doesnt apply the nbt to the item
2. The next issue is that i have been trying to add some kind of like armor xp to the armor but i cant really figure it out mind helping me? (The problem is it doesnt ad the {_o})
Thanks~

on any movement:
    set {_wantedItem} to unbreakable golden helmet with nbt "{AttributeModifiers:[{AttributeName:""generic.armor"",Name:""armor"",Amount:0.40,Operation:0,Slot:""head"",UUIDLeast:1,UUIDMost:1}]}" named "&7Divine Helmet [Lv 1]" with lore "&7---------------------||&7Armor Defense: 0.50||&7---------------------||&7Upgrade Progress: 0 / 500||&7Rarity: Common"
    if {MSpeedL.%player%} is 1:
        add "{AttributeModifiers:[{AttributeName:""generic.armor"",Name:""armor"",Amount:0.50,Operation:0,Slot:""head"",UUIDLeast:1,UUIDMost:1}]}" to nbt of {_wantedItem}       

on damage:
    victim is a player
    victim's helmet is golden helmet
    name of victim's helmet contains "&7Divine Helmet "
    lore of victim's helmet contains "&7Rarity: Common"
    lore of victim's helmet contains "&7Upgrade Progress: "
    set {_I::*} to lore of victim's helmet split at "||"
    loop {_I::*}:
        if "%loop-value%" contains "&7Upgrade Progress: ":
            set {_t} to loop-index parsed as integer
            stop loop
    set {_I} to "%uncolored {_I::%{_t}%}%"
    replace every "Upgrade Progress: " with "" in {_I}
    replace every " " with "" in {_I}
    set {_A::*} to {_I} split at "/"
    set {_O} to {_A::1} parsed as number
    set {_P} to {_A::2} parsed as number
