trying to make a autosmelt ish skript

[frogurt]

i want something where any item is changed to any item the second you get it it gets converted to something else so say i picked up cobblestone or was /given cobblestone or took cobblestone out of a chest or anything it would be changed to stone how would i do this i would also want to do this for other things like idk making coal turn into iron blocks (not actualy but i want to be able to use it for any items) i had this:

on pick up cobblestone:
set {_player} to event-player
remove cobblestone from player
add stone to {_player}'s inventory

it works but it only works for one item at a time so if you picked up 2 cobble it would give you 1 and delete the other please help me make this work please some1 any1 PLEASE

To do something like this, you'll want to set a separate variable for the amount of cobblestone in a player's inventory:

on pick up cobblestone:
  set {_p} to event-player
  set {_am} to amount of cobblestone in {_p}'s inventory
  remove {_am} cobblestone from {_p}
  add {_am} stone to {_p}'s inventory
