every item not work in item arg

[klopari]

Hello!
In this code, I can give to me diamond but not diamond block or netherite block.
Can you help me?

command /givet <item> <number>:
    trigger:
        set {_ItemVariable} to arg 1
        set {_num} to arg 2
        
        set {_invcheck} to 0
        set {_found} to false
        while {_invcheck} < 35:
            set {_found} to true if slot {_invcheck} of player is empty
            if {_found} is true:
                while {_num} >= 1:
                    add {_ItemVariable} to slot {_invcheck} of player
                    remove 1 from {_num}
            add 1 to {_invcheck}
