add an item to a list without it containing the amount of the item-

[assDawsdasdasdasd]

So in my skript i have

command /addcontraband:

 

[assDawsdasdasdasd]

sorry i have /addcontraband:
permission: op

trigger:

add 1 of player's tool to {contraband::*} 

but it always says for explain it adds 64 spruce oak planks but i want to just be spruce oak planks and not have an amount there

[assDawsdasdasdasd]

Because i have another skript that is
on pickup:

if event-item is {contraband::*}:

cancel event

but when i add something to contraband and its 64 if someone drops 63 you can pick it up
