How do i know if a player is in a list?

[AQika]

im trying to make a tag minigame, i just started and i have a dillema

on damage:
    if {tag_ongoing} is true:
        if attacker is {_it}:
            remove attacker from {_it}
            add victim to {_it}
            clear attacker's inventory
            give victim barrier named "&c&lIT barrier"
            broadcast "&c&l%{_it}% is it"

i dont know how to detect if a player is in {_it} i would love some help.

you're checking if an unset variable is something in this condition: 'if attacker is {_it}'
you may say why is it unset? it's because it's a local variable, not global

ok so let's move on on how to check if a player is IT
you have to set a global variable to the IT whenever you start the game, i have no clue when you start it, but you should that
and then, in a damage event you check if the tag game is ongoing, and now it's when you check if attacker is IT
basically.. if attacker is x... but make sure to replace x with your global variable
now we have checked if they're IT, we don't remove/add players from the it variable, cause it's not a list variable, so we set the global variable to the victim
rest of the code is fine, but replace the local variable with the global
