stop drop of specified item's on death

[BOXEY]

hello i am making a life skript rn and need to know how to stop the player from drop the life counter in there inventory

 

on death:
	if victim is a player:
		loop victim's inventory:
			if loop-value is totem of undying named "&3&lLife&8 | &7%{life.%victim%}%":
				set loop-slot to air

that's my code rn

on first join:
    set {lives::%players uuid%} to 3
    give player a totem of undying named "&cLives | %{lives::%players uuid%}%"
on death:
    if victim is a player:
        remove 1 from {live::%players uuid%}
        remove all tomtem of undying named "&cLive | %{lives::%players uuid%}%"
        give player a totem of undying named "&cLives | %{lives::%players uuid%}%"

this should work (might not knowing me) untested
