Hi _BokBok_ i was wondering if u could aid me with a skript i have been working on im kinda a noob

i want is so if a player has leather boots in there inv and they kill someone they get leather pants 

so far i have this but it not working i think its a simple skript but im missing somthing.

on death:
    attacker is a player
    if player has 1 leather boots:
    give 1 leather pants to player's inventory

i think the if player has 1 leather boots is the problem idk
