Plugin Help Kit Plugin Help

So i want it to make it that a player has to die before using another kit, but it seems to not work i get the kit with the message but i also get the message if the player was in the "list" and i don't know what to do, also i can use the kit unlimited times so its not working any advice? Im new to coding so try your best to explain it simple or post a code that i can copy but explain it so i can learn from it. Thank you
